I p/u a gs1500 over the winter,I have had no problems with it. I use it often when I'm only doing up a few rounds. It does seem like you trickle alot of powder into the pan before the reading changes though. When I compare the wieght reading with my 10-10 scale they read the same. It works great for reading the inaccuratecy of a box of some of the bullets that I use and it gives you a fast reading. I have not needed to change my batteries yet.
