Basically perfect.
What can I say!  It does it's job.  I'll admit I've only used it a handful of times so far, but it seems to work well.  It's accurate (as long as it's on a hard surface) and is as simple to use as a scale can be.  It's so light and then it almost seems like it shouldn't support my weight, but it does, and I'm a large guy.
