Shipping quickly as usual, after a day, the set was there. The Handmuskeltrainer are very good in the hand and cause even after prolonged use no pain, provided you do not overdo it. The strength is a little too tight for beginners in my opinion, but if you have a few repetitions behind it becomes easier. The springs give slight noises, are but very stable.
Full recommendation for all who want to train their hands and forearms.
