The sklz POWER SLEEVE was manufactured having the SAME CONCEPT as the MOMENTUS. That is to make the SHAFT of your golf club heavy and thus smooth out your swing plane so that straighter shots are now possible.As far as this product giving you more distance-it is highly doubtful,as it is much lighter than the momentus and the sklz power sleeve really doesnt work the muscles as much as a 40 oz momentus.The one thing going for it ,is that its portable and can fit in your bag as a great warm-up device, when your on the first tee and have no time to hit range balls..The sklz website shows this power sleeve thing attached to a driver and even hitting balls with it on the range. Well, when I took it to the range and put on a driver the results were not good:,In fact a word of caution: When this device is attached to a any club longer than three iron to hit balls, you'll have to be very careful. Because it slides down the shaft and puts EXTREME pressure on the shaft of your club.And then the extra weight of the power sleeve colliding with the range ball is NOT good for your shaft on your clubs!.. I have even heard of it snapping off long iron heads when hitting balls on the range. And as far as attaching it to your graphite shafts to hit balls?..forget about it! You'll break/damage your club and have no one to blame but yourself.Thank god I only hit three balls with the power sleeve on my graphite driver before stopping.I could feel the club flexing and could hear a "slight cracking noise".
CONCLUSION: Its a poor/portable substitute for the momentus, but DOES work and will do the same job if your in a financial pinch.AS The power sleeve costs about half as much.And as long as you dont hit range balls with the power sleeve with anything longer than a 8 iron- you wont damage your clubs.The other negative is it really doesnt stay put on the shaft. It keeps SLIDING DOWN the shaft towards the club hosel and after awhile this gets ANNOYING.
If you have a momentus keep the momentus as Momentus gets a grade of B+....This imitation momentus (sklz power sleeve) gets a grade of C+
