I've tested a lot of putting training aids over the years, from laser alignment tools to elaborate putting mats with built-in sensors, and honestly, most of them end up collecting dust in my garage within a month. So when the PuttOUT Devil Ball showed up at my door in a compact little package, I wasn't exactly expecting a revelation. It's a ball. A weird-looking ball, sure, but still just a ball.
When I opened the box, I found two Devil Balls, an alignment marker, and a small drawstring bag. That's it. No instruction manual thick enough to double as a doorstop, no complicated setup process, no app to download. I picked one up, turned it in my hand, and immediately noticed the flat edges and the design that gives this thing its devilish reputation. The construction feels solid and purposeful, not gimmicky. And at $29.99 for the whole kit, my initial thought was, "Alright, PuttOUT. Let's see what you've got." I rolled it toward my putting cup, watched it veer hard right, and said something I can't print here. That was the moment I realized this little training aid meant business.
Instantly diagnose your putting alignment issues. Our hands-on PuttOUT Devil Ball Face Angle Trainer Review explores how the flat-face physics give you immediate visual feedback. Stop guessing why you miss and start tracking your path to mastery.
Let's talk about what makes the Devil Ball fundamentally different from every other putting practice ball you've ever rolled across your living room carpet. It's the geometry. Instead of a perfectly round sphere that forgives sloppy face angles and still rolls somewhat toward the hole, the Devil Ball features flat-edged impact zones that absolutely refuse to let you get away with anything.
Here's what that means in practice. When you strike a normal golf ball with your putter face even a degree or two open, the ball still rolls mostly toward your target. You might miss by an inch or two, but you could easily fool yourself into thinking your stroke is fine. The Devil Ball eliminates that self-deception entirely. Those flat edges interact with your putter face in a way that amplifies directional errors to an almost comical degree. A face angle that's two degrees open? With a regular ball, that's a made putt from three feet. With the Devil Ball, that's a ball rolling a foot to the right of the cup. The feedback isn't subtle. It's a flashing neon sign that says, "Your face was open."
I've used face-angle tools before, impact tape, alignment sticks, even high-speed camera setups, and none of them deliver information as quickly or as clearly as watching the Devil Ball take off in the wrong direction. There's no analysis required, no reviewing footage, no interpreting data. You see the result instantly, and your brain starts making corrections on the very next stroke. It's the kind of immediate cause-and-effect loop that actually accelerates learning, and it's built into the shape of the ball itself. No batteries required.
What impressed me most is that this isn't just a novelty. The physics of the design are genuinely clever. By creating a non-circular contact surface, PuttOUT has essentially built an analog feedback system that rivals digital tools costing five or ten times as much. It's refined in its simplicity, and that's not something I say often about training aids.
One of my biggest complaints about training aids is that they're usually one-size-fits-all. Either they're too easy and you get bored, or they're impossibly hard and you get frustrated. PuttOUT solved this problem by building three distinct difficulty levels into the Devil Ball itself: Beginner, Intermediate, and Pro.
Each setting corresponds to a different orientation of the ball when you place it on the ground before your stroke. The Beginner setting is the most forgiving, and I use that word loosely, because even at its easiest, this thing is harder than putting with a regular ball. Intermediate tightens the margin for error noticeably. And Pro? Pro mode is where the "Devil" in Devil Ball earns its name. At the Pro setting, you need your putter face to be within roughly one degree of square at impact, or you're watching that ball wander off line like it has somewhere better to be.
I started on Beginner (no shame in my game), and even there, I was surprised by how many putts I was missing from three feet. Putts I would have made with my eyes closed using a regular ball were lipping out or sliding past the edge. When I moved to Intermediate after a few sessions, I could feel the improvement in my awareness. I was more conscious of my face angle at address, more deliberate in my takeaway, and more focused on a clean strike. I haven't spent much time on Pro yet because, frankly, it's humbling. But that's the point. Having somewhere to progress to keeps the training aid relevant for weeks and months, not just days.
The multi-difficulty approach also means this works for virtually any skill level. If you're a 20-handicapper trying to stop bleeding strokes on the green, Beginner mode will sharpen your face control dramatically. If you're a scratch golfer obsessing over start line consistency, Pro mode will expose every tiny flaw in your delivery. PuttOUT positioned this as an "all-abilities" tool, and I think that's an accurate claim, which is more than I can say for a lot of training aids that promise the same thing.
Let me set expectations clearly: the Devil Ball is not a tool for practicing 20-footers. Its sweet spot, pun intended, is putts of six feet and under, with the most dramatic feedback showing up in the three-to-five-foot range. If you're looking for something to help you read long lag putts or dial in distance control from across the green, this isn't it.
But here's why that limitation doesn't bother me at all. Short putts are where most golfers hemorrhage strokes, and they're exactly the putts where face angle matters the most. Think about it: on a 30-foot putt, your primary concern is speed. On a three-footer, speed is almost irrelevant it's all about starting the ball on line. And starting the ball on line is entirely a function of face angle at impact. That's the exact skill the Devil Ball trains with ruthless precision.
During my testing, I set up a simple station on my indoor putting mat, a cup at three feet, five feet, and six feet, and alternated between the Devil Ball and a regular Titleist Pro V1. The difference was startling. With the Pro V1, I was making roughly nine out of ten from three feet without much thought. With the Devil Ball on Intermediate? I was making maybe five out of ten. Same stroke, same mat, same distance. The Devil Ball was simply exposing face-angle inconsistencies that the round ball was hiding from me.
The review coverage I've seen describes three-to-five-foot putts as being "about twice as hard" with the Devil Ball compared to a regular ball, and that tracks perfectly with my experience. From three feet, anything beyond about two degrees of face error at impact was causing lip-outs or clean misses. It's a demanding standard, but that's exactly what makes it effective. When you go back to a real ball after a twenty-minute session with the Devil Ball, those three-footers feel almost comically easy. That transfer of confidence is worth every penny.
I've used training aids that require a PhD in biomechanics to interpret. You know the type of devices that spit out a dozen data points after every stroke, and you're left staring at a screen, wondering what any of it means. The Devil Ball is the polar opposite of that experience, and I mean that as the highest compliment I can give a training tool.
The feedback mechanism is beautifully simple. If your face is open at impact (for a right-handed golfer), the ball rolls right. If your face is closed, the ball rolls left. If your face is square, the ball rolls straight toward the target. That's it. There's no ambiguity, no second-guessing, no lag between the stroke and the information. You hit the ball, you see the result, and you know exactly what happened. The review consensus calls it "instant" and "crystal clear," and those are the exact words I would have chosen independently.
What makes this feedback loop so powerful is the exaggeration factor. Because the flat-edge geometry magnifies face-angle errors, you don't need to be a trained eye to see the difference between a square strike and one that's a degree off. Even small misses produce obvious directional changes in the ball's roll. This is critical for learning, because your brain needs clear, unambiguous signals to build new motor patterns. If the feedback is muddied or delayed, the learning process stalls. With the Devil Ball, there's no mud. Every putt tells you something specific and actionable.
I found myself falling into a productive rhythm during practice sessions: hit a putt, watch the roll, make a small mental adjustment, hit the next one. No pausing to check data, no rewinding video, no consulting charts. Just put, observe, adjust, repeat. After about fifteen minutes, I could feel my stroke tightening up my face, control becoming more consistent, my misses getting smaller. It's the kind of focused, distraction-free practice that most training aids promise but few actually deliver.
I want to be straightforward about where the Devil Ball lives best, because I think setting proper expectations is part of an honest review. This is an indoor putting practice tool. Yes, you could technically use it on an outdoor practice green, but its real home is your living room, your office, or your dedicated putting studio if you're lucky enough to have one.
And honestly? That's one of its greatest strengths. Most of us don't have time to hit the practice green for an hour before every round. But almost everyone can carve out ten or fifteen minutes in the evening to roll some putts on a mat at home. The Devil Ball is perfectly designed for that kind of quick, focused session. You don't need a lot of space, a six-foot putting mat is more than enough. You don't need any technology. You just need the ball, a putter, and a target.
The included alignment marker is a nice touch for home practice. It helps you set a consistent aim point, which isolates face angle as the variable you're training. I appreciated that PuttOUT thought about the complete practice setup rather than just selling you a ball and calling it a day. The drawstring bag is a minor detail, but it means the balls don't end up rattling around in a junk drawer. Small things matter when you're building a habit, and making the tool easy to grab and easy to put away increases the chances you'll actually use it regularly.
Several reviews I've come across mention the Devil Ball as a strong addition to a "training aid rotation" for home putting setups, and I agree. I wouldn't use it exclusively; you still need to practice with a real ball to maintain your feel for speed and distance, but as one tool in a broader putting practice routine, it fills a role that nothing else in my collection quite matches.

Yes, it works perfectly fine for lefties. The Devil Ball's feedback is symmetrical, a square face rolls it straight, an open face kicks it left (for you), and a closed face sends it right. No special left-handed version needed. You'll use the same ball, same alignment marker, same three difficulty settings as everyone else. It's face-angle training, not hand-specific, so you're good to go.
The warranty period is 1 year from your purchase date, standard manufacturer coverage, nothing fancy. You won't find an extended warranty or lifetime guarantee hiding anywhere in the fine print. It's pretty typical for training aids in this price range, so don't expect more. Keep your receipt and original order confirmation just in case something goes sideways. One year's enough time to know if the thing holds up.
There's no official confirmation from PuttOUT that it's approved for artificial turf. Reviews mostly show it used on indoor practice mats, which makes sense; it's a putting trainer built for flat, smooth surfaces. Could it work on artificial turf? Probably, if you've got short, level, low-pile stuff. Shaggy or uneven turf will mess with the roll and kill the feedback accuracy. I'd contact PuttOUT directly before assuming you're good.
Honestly, the available info doesn't confirm whether PuttOUT ships the Devil Ball internationally from their own store. Their product pages don't spell out a global shipping policy, which is annoying. Your best bet? Check PuttOUT's official site at checkout or hit up their customer support directly. You can also snag it through third-party retailers who might ship to your country. Don't assume, verify before you get disappointed.
The listed item weight is 0.44 pounds. That's basically identical to a regulation golf ball, which is the whole point. PuttOUT designed it to feel exactly like the real thing in your hand. You'll also see 0.2 kilograms on Amazon, but that's the package weight (remember, you're getting two balls, an alignment marker, and a travel pouch). The ball itself? 0.44 lb. Done.
So here's my bottom line on the PuttOUT Devil Ball: it's one of the most effective putting training aids I've used, and it's undeniably one of the most affordable. At $29.99, you're getting a tool that provides the kind of face-angle feedback that used to require expensive launch monitors or hours of video analysis. The fact that it delivers that feedback instantly, with zero setup, through nothing more than clever physical design, that's genuinely impressive.
Is it for everyone? Not quite. If you're a casual golfer who doesn't practice putting at home, it'll sit in a drawer unused. If you're only interested in improving your lag putting or green reading, look elsewhere. But if you're a golfer who loses strokes on short putts, and statistically, that's almost all of us, and you're willing to invest even ten minutes a day into focused face-angle practice, the Devil Ball will make you a better putter. Period. I was skeptical when I pulled it out of the box, and I'm a convert now. The thing just works. It's simple, it's humbling, and it delivers exactly what it promises. That's about the best thing I can say about any training aid.
