I have NEVER heard of any UPS that actually works as long as claimed when the power goes off. I just have my tower and an LCD monitor hooked up to mine and I think it shows on the display that it will go about half of what was claimed.However, it has worked flawlessly and it was affordable. I'm glad I bought this as it makes me feel pretty secure about my computer hardware and about the prospect that I'll be able to save any new data if I have been lazy. I'm usually a sav-o-maniac anyway, but it doesn't hurt.I have read many "expert" opinions on this subject, and they ALL say, "Get a UPS!!!" This one is a decent choice. Your surge protector won't really keep your computer safe.
