I noticed that lots of reviews mentioned the knurling on these grippers to not be up to par with Captains of crush. And I agree that they cannot compare. However, as I myself own a set of Captains of crush I actually think the knurling on these grippers is perfect. For Captains of crush I've noticed the higher the rating # the harder it is to crank out sets because of the knurling. With Xzyppci grippers the knurling is just right where I can take the 250lb gripper and crank out a few reps. The knurling allows my fingers to slightly slip along the handle as I continue to close them therefore allowing me to close them and repeat. The Captains of crush knurling prevents my fingers from doing just that. I have to set it with my other hand and then crank out the reps. With the Xzyppci grippers I can grip them with one hand and close. I use my Captains for force holds and my Xzyppci grippers for reps. Plus the value for the money. You can't beat that. Read more

Based on the photos I was expecting to get these in a box that I could also store them in. They actually came in bubble wrap and a zip-lock. Not impressed. The grip trainers seem to function as expected. Read more
