Customer Reviews for APC - Back-UPS 850VA Wall Mountable UPS - Black

Verified Purchase:Yes
This is a nice unit that I use for my Harman P68 wood pellet stove. If my power goes out I will have about 15 minutes to turn off my stove so the house doesn't fill with smoke and ash as what would normally happen. To me this was worth the money to have that kind of protection.
Pros: Energy Efficient, Ease of Management, Good Value, High Confidence Level in 24/7 Uptime
I would recommend this to a friend!

Great hardware, fairly priced and shipped quickly. Works perfectly protecting sensitive gear and shuts PCs down in an organized fashion should an extended outage exceed the time capacity of the backup batteries. Good gear!
Pros: Easy to Perform Maintenance, High Quality, Fast, High Confidence Level in 24/7 Uptime

Have used APC Back-ups for 20 years due to reliability--originally as small business owner and have continued to use at home for computers and entertainment center since retirement.

I cancelled the purchase due to a mix up so no reason to ask me, right?

It used to be easy to register and look at your purchased devices. Now that is very difficult and often impossible.
Shame on you
