That’s the one I use. I use it everyday, usually several times so I get my money’s worth. I don’t think it over-estimates rice, but I haven’t compared it to anything; my BG’s are good after I eat rice though. I rarely eat rice, and usually I eat brown rice. Are you just talking about white rice or brown rice too? How did you determine it’s over-estimating?
I don’t like measuring cups for anything but liquids. I measured oatmeal once, and then weighed it, and found there was enough of an inconsistency that I only weigh it now. Most things are apt to have volume variations, and that annoys me. Weighing it solves that problems.
As for the scale, I like it overall. I agree the buttons aren’t as user-friendly as I had hoped. I also have some difficulty reading the screen unless it’s at a certain angle, but I think that’s more due to vision issues I have than the scale. I’ve had this one for about a year, and I like it enough that I’ll continue to use it until I stumble upon something I like better or it breaks.
