Query: Inexpensive and it works...

I have two of these, the most recently purchased one bought through Amazon is to protect a new office printer. The oldest one functions as a potector for my projector in the media room. I originally purchased this due to size, protection warranty, and the fact that it worked well in a ceiling application (it helps that it has indictor lights that show if there's a problem that you can see from the floor). It's been doing its job admirably through many power outages and surge situations. I felt very comfortable purchasing a new one for an office application.
