Input:
This is great if you want to advance over the basic grip trainers. I had a grip trainer that went up to 90 lbs and it was very easy so I ordered the 140 lbs Captains of Crush and it's hard now but after training with it I'll be much stronger. Great build quality and received quick, only 1 day after it shipped.
