I bought the trainer last month...was very dissappointed! Too damn easy ...hell my wife could close it..so i bought the #1 ...much better...can now do it for 17 reps...gonna buy the # 2 when i hit 20
I've got the 1 and 2. Started with 1, could close it right away. Ordered the 2 the next week. Not too bad. I've also got the Ivanko Gripper. It's also very nice. I consider these more of a test of grip strength or a challenge than something to increase strength. Just my opinion. If you want to get a strong grip do Farmers' or use a thick barbell.
My .02 worth.
