Aiuto per la tua mano. Se ti manca la forza per stringere con la mano, se a volte senti le mani indolenzite,...con me, funziona.

Bin sehr zufrieden, tun was sie sollen!

Pretty fun. The O are my most used items though.

Found these on an instagram post , had lots of tennis elbow and forearm problems from the gym and started using these and they really help , come as a set of various strengths . Great product and a good price

Had these for about a month now and I am noticing significant improvement in my hand strength and reduced pain from a multiple years long repetitive strain injury. I haven't had issues with durability like some other people have reported but I have very weak hands so it's been great so far. I think this is a great product for anyone who has been struggling with pain or lack of mobility in their hands.
