This unit has been working fine, and I like the self-test feature. The one significant drawback -- based on my reading of other reviews, this unit is not alone in having this issue -- is that the damn thing smells quite strongly, something like the smell of new plastic. At first I thought the plastic case was just made out of particularly smelly plastic, but in reading around, and now through personal experience, it seems to be related to the charging process. The battery must be releasing something, or the heat of charging is making the case or other parts smell. Someone else reported their Belkin unit stopped smelling after about a week, mine is now a week old and smells less but definitely still smells. An unexpected bummer. I was getting tired with APC units failing, so I tried this unit for a change. I hope it lasts a long time, but only if it stops smelling!

Update: It stopped smelling after about a month.

My unit came in DOA. Will have to RMA it. After getting it in DOA, which is rare as most companies actually test there units before sending them out, I checked out more extensive reviews on other web sites where many complained of the unit working for a period of time (weeks to months) and then just shutting off while they were in the middle of working even though there was no power loss. Others complained of the smell. I fortunately did not experience either of these issues as mine would not even power up at all.

There are units from Eaton available for a similar price that are much better quality would recommend these over this unit or its cousins.

I purchased this unit in Jan. 2010 to backup my desktop PC. It powered off by itself so often some of my files got corrupted. Tech support insisted the unit was overloaded by my PC which draws less than 300W and within the limit of the backup unit. This unit even powered off when no equipment plugged into it. I switch to another brand with similar spec and have no problem at all.

This UPS worked for a while. I used to come home everyday and turn it back on. It will just turn off with no warning. It was only protecting the phone and cable modems, so it's not critical. I couldn't call home sometimes, because it went immediately to voice mail, and so I knew the telephone modem had no power again. I finally came in today and unhooked it. I have replaced batteries in these type units before, but there won't be any need to do it on this one, as it didn't last long enough to bother. There won't be any Tripp Lite products for me from this day.

got this for my LCD TV , when the power goes out it gives you time to shut it down without any damage , protect your investment get one !
