I have a Tripp-Lite LCR 2400.

I've had it for 2-3 years now and it has been working flawlessly. On the other hand, I can't recall that we've had any brownout conditions in this time frame.

I hid it on top of my entertainment center where it's not visible.

Note that it isolates outlets from interfering with each other-just noise, not ground loops.
