Input:
Amazing hand gripper. High quality, very durable. Like any posession, be sure to take care of it, preferably with an oil based lubricant like WD-40 or mineral oil, so it stays in good condition. Challenging for the average man. It took quite some effort to close this when I got it. Now I'm closing it 12 times with each hand. Just follow the training guidlines included with it, and you'll have a crushing grip in no time.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
