How come you cant say its true?

A true AVR will maintain a 220VAC output whether the outlet goes up or down
It's a difference between having some regulation to not having one at all. And at around P300, I wouldn't call those cheap AVRs a sham... This is the point I disagree with you.

It's a budget AVR, no more.

As I've said, even cheap AVRs do afford some regulation. It may not be the best nor does it go anywhere near your definition of a true AVR, but it does the job up to a certain extent without spending a few thousand pesos.
