Finger Exercise Grip Strengthener, Finger Stretcher Hand Grip Resistance Bands Finger Extensor Exercise Bands for Carpal Tunnel Guitar Pianist Rock Climbing Tennis Trainer 8PCS

Easy to use?After a couple uses, I kind of learned how to slip these on really easily. Just take your pointer and middle finger to help push down. When I started with the lowest, I immediately felt it in my muscles in my forearm. I don't recall if there were any instructions, but kind of created my own routine and have built up to the last band so far in the first set. Spending 2 weeks per band.Comfort?Is it supposed to be comfortable? It's fine and no issues.Durability?My own issue is that these aren't really made for people with slightly larger than normal hands. The only reason why I've stepped up in band strength was because I end up ripping the part of the band that connects the thumb and the pointer finger. Would have been nice to do some drop down stretches with a lower band strength.Overall?Ignore the Instagram videos of some dude with veins and it tells you you'll grow 6 inches in height and have models rub your forearms after using this for a month. Honestly, coupled with a regular hand gripper and routine, I have noticed a pretty good improvement of my overall grip strength and durability. Has assisted with rehabilitating a previous thumb injury, but I would say results may very.
