I have used $50-$70 Belkin surge protectors before (110V)...joule rating was in the thousands...they even guarantee your equipment upto XX,XXX dollars...I bought mine in the USA. In general, the higher the joule rating,
the better the surge protector.
My brother plugged it accidentally into 220V while stuff was connected to it...all the appliances attached to it blew.
I wrote a super angry letter to Belkin...told them "there was something called a 5-cent fuse". They told me by plugging it into a 220V outlet I "beat" their system. Wow..my kid brother just defeated their entire product line.
No money came my way of course. Lousy piece of junk!
Luckily, the stuff attached to it blew their own fuses...something Belkin didn't engineer into their 110V surge protectors. I replaced the fuses myself and told Belkin I would publish their email in the web.
Octagon (Megamall) sells the 220V version locally at about P800+.
A computer store in my place is selling this BELKIN surge protector and the salesman claims it does also well on audio/video system. Anybody familiar with this brand and make some comments? tnx.
