I got this Mitsui Computer AVR about 10 years ago as part of the computer package that I got from a local computer store. And for the last 10 years, I have changed computers twice already, but this AVR has stuck with me.
In our country with the many power fluctuations and interruptions in just a single week, we need an effective and efficient AVR to keep the computer from crashing. This coupled with a good UPS, I was able to keep my first computer for 8 years. Now my newest computer is already 2 years old.
Although I got my Mitsui unit for free (or at least packaged with the cost of my computer) when bought separately, it is very cheap. For the same unit that I have got, it costs roughly less than $8.
It is IC controlled, with surge suppressor and AHVLC.
