These are good to start this type of exercise with since compared to others I have since purchased they are ....easier(??). I have trigger finger and began using these for that. Yes...these will help (massage and stretching for tennis elbow/carpal tunnel will also help). The balls are useless for my issue but the bands used without the balls were a good starting point as mentioned. I have worked into the “five circles hooked together style” which seem to come in more pounds of pull and also work the thumb a bit more effectively than this longer style did. Have trigger finger? Definitely add these for a couple sets every day. I can keep my “trigger” down when I do all three things regularly: stretch, forearm massage and finger extension exercises.

Right strength

My physio recommended this to fix a tennis elbow injury and I had very good results.However, it is not very durable. Red ball developed a crack on day two and, while I was still able to use it for a while, it finally gave in on week 3. Same for the elastic band. Both the black and the grey bands snapped at the thumb position. I do have thick fingers. To their credit, there are two sets of rubber bandsOverall would recommend it but not impressed by the materials

I only just received this so I can't comment on if it helped me. I'm not sure if that would be useful though because everybody is different. I can say that the balls feel too small for my hands/fingers. To be fair i do have large hands and longer fingers than average. I wish they made a version with bigger balls that fit my hands better. Besides that the quality seems good and it came with informative instructions.
