Ordered the strength grip it's a brute at 55lb to 170+lb pull. I tried it soon as it came in and wow, I bit off more then I can chew, at 80 years this is way out of my league , so here it is. I paid $89.00 for it squeezed it one QUICK session and that was that, if you want strong forearms this is the ticket . It is absolutely perfect with less then 3 mins on it. Cash only, no funny money CRYPT . Thanks for looking.
