I find that they are accurate for bf% HOWEVER, you MUST read the instructions when you buy the thing. You cannot have had any alcohol within, I think, 24 hours. It also says you're not to have worked out in x amount of time...etc. etc.

I have a Taylor one and it just isn't as accurate as my friend's Tanita. One day I woke up and it weighed me at 113lbs! I said, "wow, so that's what 113 looks like on my scale! - guess it CAN actually go down, at least! Thought it had been stuck " It was too low to even fool me for HALF a second. I have hated that damn thing ever since.
