Guess I have been lucky. I bought my 1200 years ago and it works like a champ. Only button problem I have is I have used it so much I have worn the print off of the enter button..
I for one was very glad to retire my beam scale to the closet and hae not seen it since. I check the scale often with a bullet of known weight and the scale is spot on. 2 kernals of H-1000 is 1/10th of a grain and it measures it with extreme accuracy. That works for me.
