bought one new years ago. It was a piece of crap right from the git go. I would get readings about every 3rd or 4th shot. I bought it to replace a piece of crap chrony and thought i was buying a good unit. Ive got two of there scales and a dispensor and they work great. Well it sat on the shelf for probably 5 years because it was about useless. I took it out the other day and couldnt get a single reading from it. I said enough. I bought a competition electronics from midway. Put a battery in it and took it out yesterday and it worked perfectly. Only down side is no remote reading. It has a deal that will pair with a bluetooth phone but this old cogger still has a flip phone.
