Im a pretty avid weightlifter and that seems like a waste of money. A glorified strap that advocates strength gains . . . I dont use gloves or straps but if you feel like using something I would say try some straps. The site you listed stated something about "sore hands," ive never had sore hands so im not too sure what thats about. Basically don't waste your money. Go buy yourself some gloves or straps for 10 or 15 bucks. As Thaikim stated, unless your lifting some SERIOUS weight like maybe big deadlifts or shrugs then you really dont need anything.
