Never came ...I've been waiting on it to arrive and its been so long i forgot i even ordered it until i got a charge on my card. Don't know whether or not it was taken off the steps by a package thief...or if it got delivered to the wrong address. But I got nothing and my credit card was charged anyways. Could use a refund.
Pricey but well worth it as it's a quality device.
Very Good Product! i'm Very happy with it :)
The one The only The Best of The Best :)
Beautiful in your hand or on your desk. It feels like a precision tool.
I wish the manual was a little more detailed. I seem to get more power when I don’t use my little finger.
Is a good way Forward training yourself arms
It's great. Heavy duty. Quiet. Easy start. I used to have one that had a string. This is way better. Great case. Quality product. Thank you!
Very good for recover after ingury!
Finaly, I buyed it and I'm not disapointed. It don't looks like a toy! It's well designed and I feel that each part has been studied. It's heavy in my hands, i'm not affraid about breaking it. It's really a nice product for your arms muscles, believe me. My wrists are too stiff. Ghis powerball does a very good job about that. I also used the titan version during a sport training far from home and I was immediately surprised by the quality and the efficiency, that's what made me decide.
Your products are very good in general, but I personally find them expensive. Especially, since I already broke the plastic between the shells of an Powerball 280Hz Classic Blue and an Powerball 280Hz Autostart Pro, only by using them (without any accidents - just by pressuring them with my hand). Hence, my purchase of the Diablo model.
Great quality and even though it's a bit expensive compared to other powerballs, I'd say it's worth the price. Small and easy to bring anywhere. Very quiet, smooth and enjoyable to use.
The Diablo powerball is smaller than the Hybrid. Not much but enough to fit my hand. Also a little heavier and produces more force. Really great!
