I use this clamp 5 days a week, all day and love it. I am left handed and it works well for me. I own two Park Tool repair stands with their clamps, but this is the clamp that I use. The ratchet sound is vaguely satisfying, but the one hand push button release is great. It easily fits into the Park stand receiver too. The only reason I am not giving this clamp a 5 star rating is because the quick release in not on the front of the clamp.
