If you do some research you'll find that weber rounds their magnet weights so 40oz is really about 35oz. On another note all I care about is sounding the best while spending as little money as possible to do so, I could care less if someone that I will never meet is a good guy. And I doubt some d-bag sales associate at guitar center ever wanted my business because I was a good honest guy. 99% sure these are scumbacks, and will order some soon.
