Query: I would give it a zero if I could.

I just purchased this product - and on the first pine board I upholstered, it stapled MOSTLY flush - I did have to use a hammer to get it the rest of the way down. About 30 staples later, on the second pine board, it was starting to stick, then eventually jammed to the point of needing pliers to remove the staple. I DO NOT RECOMMEND!!
