Has anybody had any issues with this scale not weighting until it hits 5 milligrams and the numbers jumping around?

I've had problems as well. When turned on and left to warm up it usually sets to "0". When I add reactants to the scale it doesn't move, then suddenly jumps to .006, then .007, then back to 0. It stays at 0 even when I add a little more. When put on the high priced scale it reads over .010, so this isn't good for anything small, certainly not a ",001g" scale. The other suggestion that one would use the 10g test weight, with the pan and then add the reactant doesn't work either (I didn't expect it to). This doesn't work as told.

Does this scale have an option to measure in carats?

Yes, but although the scale reads to milligrams, it's accuracy as listed in the manual is only .020g, or a tenth of a carat either way.

The material I weighed seemed to stick to the weigh pan. Any suggestions for this and also keeping the scale on long enough seems to be a problem

Place a sheet of paper/wax paper on the little pan before use. I encountered this problem when weighing out my nutritional supplement powders. Balance a small square pane of glass or acrylic panel on top of the pan provided and place your sample on top. Anything that sticks can be scraped off and recovered using a razor blade.

where can i get replacement tray & tweezers?
