I don't recall, but I didn't find any reason to believe it wouldn't be at least as accurate as I need it to be. It cost me very little, so if it's a total pile, I'm not out hardly anything.

We have a really nice, high-dollar postage scale at work, in addition to our larger shipping scale that I usually use, so I can check weights against that to see how accurate it is.

I really wanted the thing for weighing out food prior to trips, for which a super accurate scale is not really necessary, the thing is only a 500g (1lb) scale, so I'm really not going to be weighing anything important on it.

Like I said, cheap, and if it sucks, not a big loss.
