I've ordered from Ironmind multiple times, either through Amazon or their own site and both their service and quality are impeccable. I've bought their dip belt, neck harness, lifting straps and multiple Captain of Crush grippers and their products will probably outlast me.

The Captains of Crush grippers are far superior to anything you can buy at your local sporting good store. They are solid metal, not plastic, but the knurlings make it so it's easy to grip. But that's the only thing easy about them because for an average male, even the Trainer will give your grip a solid workout.  I have the Trainer, 1, 1.5, 2 and 2.5....was able to work with the 2's a couple of years ago but my grip atrophied a bit. I'm using the Trainer to work my way back slowly, serves as a good workout on its own or a good warm-up if you want to work with the 1's and 1.5's.
