I’ve had several over the years. In the event of a power failure it gives you time to log off and turn off computer without having a cold shutdown. Also helps with power surges.

Perfect

This is not a product that you can tell you like until there is a problem. So far so good

I went through part of the return policy steps as suggested by tech support on my older unit. There was no savings so just bought it new and keep replacing the batteries on the one out of warranty.

I replace more batteries that never work in these. For the small convenience of being able to shut the computer off "properly" when the power goes out. Might as well just not use one. You will replace more batteries then it is worth and the time/money spent could go for a new computer. Oh and you can't really ship or dispose of these LEAD batteries.But a good computer and it won't die when the power goes out suddenly.

I tried to return it the day I got it!My old one started working again.However, I tried to return it directly to Amazon, because it had a Battery, they would not accept it..The seller will refund me the cost of the item, but will not cover shipping, across the country!California to New Jersey is a long way for a heavy item.It could cost almost as much to ship it back!Be careful with items with Litium Batteries!!,

Lower left top corner of the unit melted while I was out of town. The battery was also dead.
