Product review (5 stars): Easy to read buttons was top priority
Easy to read buttons was top priority.  It doesn't glow in the dark, but that wasn't really a problem for me. Humidity is always a problem around my house, and I wanted to get something that would easily tell me how humid it was.

it's unobtrusive and has a little gauge on it that tells you about where you want humidity to be at.  Different conditions require different levels, so this can help you shoot for exactly what you want.
