Needed a UPS for a wireless extender and surge for a laser printer. Works as expected.

Bought this after the power went out a few times and lost some data. And as usual the power has not gone out while on the PC so all I can say is it works well as a power strip and when the power does eventually go out, I'll update this review and let ya know how it fares

This backup battery/surge protector does what it's supposed to do and that's protect my equipment. No problems with it - the only complaint is that some of the plugs are difficult to get in the outlets and then get out of them, but other than that, no complaints.

Good but alarm is annoying

Only drawback to me is that there is no option to turn off the low house voltage alarm. House voltage transiently drops when certain appliances turn on and this UPS will alarm (it's loud). I set the sensitivity to the lowest setting but it's still too sensitive.

Highly recommend this device to save your components & prevent losing current projects you may be working on when there are power glitches. We are in a rural setting & constantly have power surges/failures.

I purchased a couple of these for point of use backup. Used behind routers,hubs and Poe injectors. Work like they should. Wish they could be tied into network for control and monitoring. Also wish they were not so bulky. At this price though...can't complain.

I use this unit for low power items like my laptop, small printer and modem. I have a much larger unit for my tv and gaming systems that I will be reviewing soon. It works great, I suggest a less delicate setting to lessen audible surge alarms.

I bought this mainly for my internet connection. We have a lot of short shutoffs and all of a sudden my router and modem are resetting. My computer is on another UPS already, on the other side of the room. This has worked exactly as I expected.

This is a compact enough UPS unit so that it doesn't take up too much space, but it yields plenty of time to do a complete system shutdown with ease in case of a power outage. Also does well against power spikes and brownouts. A good choice!

We live in a old building. So our electric wiring is old as well. If we put on A/C and microwave at the same time, the power is shutting down. Computer, TV, Internet - it's disaster! .. Now I have time to restore my power without interruption. It is great!!!
