I had a Surge Guard for a little over a year. Used it 24x7. No issues. But I have no clue how many times it might have taken "hits". Then early this Summer, went camping, plugged it in and ... nothing! Dead. Since it was over a year old it was out of warranty. I started looking a Progressive.
Progressive was a bit cheaper, but also came with a life-time warranty. I've had it plugged in 24x7 now also. So far, no issues.
Mine does not have all the advanced read-outs. I don't need all that stuff, and actually don't care. If the Progressive protector kicks off, I know there is a problem at the campground. I'll call the park service to check out the electric post.
I suggest getting the Progressive, after having had both now.
