I bought the 50lb grip since I already had the other sizes. For average adult male, 50lb is a minimum starting grip size, 100lb is also ok starting, and 150lb is tough to start with. So difficulty range is good match for most guys. I don't expect to ever hit 200lb or above, but who knows. 2 issues. FIRST: The fit to the hand is tough because the handle shape is straight. A handle shaped to your hand would be better. Diameter is ok, but squeezing pressure is uneven with most pressure on the middle and ring fingers. Pinky finger may or may not be on the grip since it is a weak finger, and you get the most leverage from the fingers at the bottom of the handles, so you might drop off the pinky and move the ring finger to the bottom position. Uncomfortable but no disaster. SECOND: There are 2 1/2 turns in the center turns of metal, this is where the bending take place when you squeeze. My 50lb unit has those center turns too close to each other so that you can feel them rub together. My 100lb unit from a different supplier has more space between turns and does not rub. Unecessary issue and would be easy to fix during manufacturing at little cost. Annoying but no disaster.

Great grippers, perfect for grip strength

I bought a hundred pound strength which was a bit much. This one feels perfect for me. I use these as a teenager similar ones that were a little bit stronger than this but not by too far. I kept both pair. Originally bought some from Target last week and they were like butter. I don't know if they were even 1 lb resistance. I gave them to my wife.

Es perfecto, cumple lo pedido

Works well, but after a day or two it really hurts your fingers.. not in a good way. I’m using it with the rubber grips on and it still is very uncomfortable.
