I have an old clicker I got from Harbor Freight in '73. I used to have it checked once a year and it was always within a couple of pounds of being correct,close enough for me. I'd give it to the Snap-On salesman,and he'd take it to Salt Lake City with him and get it checked when he went to pick up his orders and drop off his warranty stuff. When I left the shop,I couldn't do that anymore,so I don't know if it's still close or not. I never got him to tell me where he had it checked-guess I'll have to check into that next time I go over there.
