Only had this a few days, but it seems to be a solid product so far. I specifically tested it for repeatably based on some negative reviews here on Amazon, and I found no issue. Several various measuring cups tared correctly, and kept proper measurements on the grams scale as I moved the container from side to side on the surface.
I have no calibrated weights to test with, but one measured cup of water and two measured cups of water in a correctly tared measuring cup both weight within 1gm of the expected weights from some "standards" site I found.
So overall the repeatability and accuracy is well within what's necessary for baking a loaf of bread.
EDIT: So far I have been using this as my primary kitchen scale for about six weeks. It has not disappointed me. Granted I am not a heavy user, and this is not a commercial product. It is designed for people exactly like me, 3 - 10 uses a week use for critical measurements like baking, and it works perfectly for that.
I have not noticed the lack of repeatability that some others have complained about, and the consistency of my baking has improved dramatically.
I am pleased enough that I just bought another one for my daughter.
