Humm, I didn't mean to start a fight! While I totally agree that it would be nice for all devices to have surge suppression built into themselves, and it isn't all that expensive to do it, in today's market, those extra steps just aren't often taken. There are lots of things that can put higher than design voltages on the power lines within a home, some internally generated, some from external. Solid state junctions will get 'chipped' away at by those spikes, and may not die immediately, but each surge can be one more chop with the proverbial axe. Many of the better strip type surge suppressors also have noise filtering on them, and that can make a difference too. While the device I installed doesn't have noise suppression, I didn't feel that was a requirement for what I was trying to accomplish - keep my 85-year old mother from having to replace the circuit board for her frig, or buy a new microwave again as a result of a storm. I'm hoping the effort is fruitful. I thought others might find it useful, as they have been around for ages, but don't seem to be installed all that often, to the homeowner's detriment, in my opinon. I'll still use a good noise filtering suppression strip at high dollar thing like a plasma tv and computer, but the extra level of having the incoming power clamped to acceptable levels seems like a good first step.
