If your power is constant or fluctuates only gradually the AVs 2000 will remain spot-on. If your power fluctuates rapidly or flutters it may have problems keeping up. I use mine with my projector to protect the bulb. For this application it works very nicely.
Very occasionally my unit get "hiccups" and makes clicking noises as it attempts to deal with power fluctuations. Just like any computer, disconnecting it temporarily from AC for a "hard restart" usually solves the issue.
