WOD Nation Adjustable Hand Grip & Forearm Strengthener - 100-300 lb, Platinum Black, V-Shape Wrap Handles - Wrist Strengthener - Hand Gripper Trainer - Heavy Duty Grip Trainer Set - Fitness Equipment

The lowest spring is tough enough to start out with. I'm 63. I was always very athletic. But the last 5 years have been tough. A number of physical conditions have changed me. But, I'm getting back on the right path starting with getting my hand strength back. I've had the gripper a week and in about two weeks, I bet I'll move up to the next spring. Great improvement.

This is has to be a record on how fast these things broke. As soon as I took it out of the box and threaded the handles on, the metal threading broke (they are glued on to the resistance coils) and now it is stuck inside one of the handles.

The second spring of five (150-lbs) has failed. The threaded insert that permits the handles to be attached has become loose, causing the spring to be unusable. It will be hard to advance my grip strength in that I now have to jump from 100-lbs to 200-lbs. I’ll try to return for a replacement of the same set because it is an awesome product.

Estoy contento 😀 es lo que esperaba son suficiente fuertes hay que aplicar mucha presión para que trabajen me gustaría

I bought it, it broke, so I returned it. I ordered a replacement figuring maybe it was just a simple manufacturing error and I got a dud. Nope! Broke again in the same place. Glue doesn't hold the threads on hardly at all. Don't buy. Find something else to use.Also the weights aren't listed on each spring. Horrible product.

It was stated in a lot of reviews that the springs were unmarked and could not tell them apart.Well, if you weigh them on a kitchen scale and set them in order lightest to heaviest then mark them with a silver metallic sharpie as I didyou just solved the mystery.1=100 1.5=150 2=200 2.5=250 3=300

The glue holding the threads to the spring comes loose from tension. Perhaps using a stronger glue or epoxy will work. I am gonna try to glue it back but it sucks to have to fix an item 2 days after receiving it.

Pretty nice set of hand grips, but they were too difficult for me and I returned them. Probably be great for someone younger and stronger!
