FIITY 18 Pounds Resistance Adjustable Rotator Machine for Upper Body Strength Training, 360 Degree Rotating Grips, Multifunctional Spinning Burn Machine for Forearm Trainer, Boxing, Workouts (Black & Sliver)

After using this for a few weeks, I’ve gotta say—this thing is a beast for forearm and upper body training. I read some reviews before buying, but they didn’t quite capture how effective (and addicting) this little device actually is. So here’s my honest, detailed breakdown:[Build & Design]The construction is solid—full metal body, smooth bearing rotation, and a real sense of durability. These aren’t cheap plastic spinners. The weight feels just right in hand and the grip is comfortable even when your forearms are screaming. The grip texture gives you enough control without tearing your hands up.[Adjustable Resistance]This is what separates this tool from a lot of the junk out there. You can adjust the resistance with a simple twist mechanism. Crank it up, and your shoulders, wrists, and grip will feel it in no time. Drop it back down and it’s a smooth burn—great for warmups or rehab. Super versatile.[Functionality & Use]You’re working all the little stabilizers in your arms and shoulders with this thing. It’s like a forearm blaster, grip trainer, and shoulder stabilizer all in one. I use it mostly for:Post-jiu-jitsu recoveryShoulder stability workForearm pump before liftsKeeping my wrists strong for grappling and boxingPro tip: go slow and controlled—don't treat it like a toy or you'll wear yourself out in 60 seconds flat.[Noise & Movement]It’s surprisingly quiet. The internal mechanics don’t rattle or click like some cheaper versions. Rotation is smooth and predictable. No weird wobble, even when you turn up the resistance.[Storage & Portability]Doesn’t take up much room, and it fits in my gym bag easily. If you travel and still want to get upper body activation, this is perfect.[Final Verdict]If you’re serious about grip strength, injury prevention, or just want to add something different to your routine, this is absolutely worth it. I was skeptical at first, but now it’s part of my regular workouts. I’ve already recommended it to three training partners.Would I buy it again? No doubt.

Unique piece of quality made contraption.l! Won't deny that I thought this plaything might of become another waste of useless workout toys out there. Boy, was I wrong. For one, it works 💪...you will feel the burn. Guaranteed. The more often you work it. The more you'll not only last longer but see and feel increased performance.

Great item! 💪💪💪 - 12lbs is not for beginners.

If you're looking for cardio and to build your endurance keeping your hands up for LONG periods of time like for boxing, I suggest getting the lighter one.For me, the heavier one is for weight training and more for building your shoulders.This particular weight (18lbs) is pretty heavy once you lift it above your shoulders doing 40 reps. It's more for the intermediate to expert weight trainer.But honestly, if you're a boxer I suggest getting both. Use the lighter one for maximum endurance (10x40-50) and finish it off with a few reps (3x40) of the heavier one.It's really solid, feels like a professional gym equipment. Pair perfectly with my PowerBlock.Gives you every nice burn and pump.

I’m kinda on the fence with this product. Definitely feel the burn but it’s torquing my elbow joints in an odd way. Deducting one star for that and one star for the high price of $160.

I’m quite pleased with this device! It can be stored easily. It’s sturdy and heavy duty (not lightweight at all). I get a good workout in a matter of seconds! I feel it in my arms, abs, and back. Great for work-from-home. I highly recommend, if you enjoy fitness challenges and want to tone your upper body.

I love this piece of gear. I go 30 seconds on / 30 seconds off as hard as possible at eye level for 10 minutes. Burns like you can't believe for the last minute or two. Great workout. I am mostly a grappler but got into boxing recently so have been working on my strength and speed striking. This helps. It is a cool, durable, overbuilt hunk of steel that is great to keep handy at work to sneak in a little workout when you can.

Quick and intense feeling of working out. Great arm and shoulder workout with the sensation of core building and tightening.
