Yep, spend the extra and get a better one. I got one, and same thing, wouldn't update when I tried to trickle charges, and it wouldn't hold zero for more than a few charges. Have to keep putting the empty pan on it to check for zero before dropping the charge. I don't have any experience with any other digitals, but I would think that the Pact or RCBS would be good. After that little trial with digital I decided that the good ole balance beam scale wasn't so bad after all...
