does as it says on the website, slide item onto second knuckle to achieve good results, definitely helps with hand strength and tendons in forearm (works for me), good quality and value for money

Exactly what I was looking for to help strengthen my fingers. They're cheap, easy to use and do the job. My only issue is the difference in tension between the lightest one (green) and the medium one (blue) feels like quite a big step up in resistance. It would be even better if the blue one was slightly lighter.

It is a brilliant idea to come up with these and even more brilliant to provide assorted strength levels (3, 4, 5 kg). They work like a dream. They are a great complement to my exercise routines. You can fiddle with them anytime: in bed before sleeping, on the bus, on the plane, in front of the TV, etc. The cherry on the cake is they are solid quality, easy to fit, and very cheap.

not to good

Helped with muscle/ligament injury

These are very good for strengthening hand muscles tendons et cetera, when especially used in conjunction with the softballIt’s very hard to keep up consistency and do it daily, but they do work

The media could not be loaded. Initially thought there's too much resistance but on messing about with them & sliding my fingers all the way in they offer fantastic resistance for all extensor exercises...This is helping me get over a condition called dequervain’s tenosynovitis... 👍

Really good for my fingers pleased with these bands
