Rated 4 out of 5 by DenisO не совсем то что хотелось
Продукт по качеству сборки находится между 3 и 4. Родной шнурок для запуска без узелка неюзабелен, а с узелком периодически застревает. С руки запустить пока не удалось ни разу. Советую смотреть на более качественную модель, желательно со счетчиком. Иначе не совсем понятен результат тренировки.

Rated 4 out of 5 by MADGeorge Very good for forarms
This Powerball is a great workout for your forearms, within minutes of getting it up to speed my arms were struggling. Definitely does what it says on the tin.
Did however get the string caught while trying to start it as the groove isn't very deep, but eventually managed to free it and it worked fine afterwards.

Rated 4 out of 5 by Anonymous Awesome bit of kit!
Have had this item a couple hours now and it is Awesome! Really works the whole arm depending on how you position your self. Way more powerful then I first thought. A real steal at £11.99!! If you use your arms to do anything then buy one.

Rated 5 out of 5 by Anonymous Surprisingly effective
Great tool to increase grip strength. Requires nothing but time and effort. Effect kicks in after very few sessions. Great supplement to 'live' training on your bike.
