    Replacement

    Bought this to replace a unit that failed - internal battery died - instead of replacing battery. Went to all local battery stores and none carried this specific battery. I've didn't want the hassle of drilling and mounting a different model and have since found batteries on-line. As a UPS and surge protector it has worked fine.

    Bought this to use as a backup for my modem & router. It has worked very well and is small enough to fit in a few more locations than some other larger backups.

    I picked this up to protect my son's gaming computer. It was only a little bit more than a surge protector and provided battery backup as well. It was a good investment that comes with a guarantee. Recommended!

    I waited a long time to get this, but I'm not sure why. Great power-backup device for the price. Using it for all of my routing equipment and my two main PCs.

    I have been using APC products for close to 10 years now. The price is reasonable for the amount of use I get. Would purchase again. I like that the number of possible outlets has been increased from 6 to 8. Using these products with 2 flat screen televisions with surround sound and gaming consoles and a desktop pc. The number of available outlets is critical in this case. very happy with this product.

    I have my desktop and monitor and modem connected to this UPS. If the power goes out I have enough time to save my work and shut down the PC gracefully. This UPS Battery Backup does what it is supposed to do.

    I was looking for a device to allow cable box to ride through power blips w/o losing programming. UPS system was not available at store and circular photo looked small. I was surprised when it arrived at the bulk, but couldn't argue with the price. It has already saved TV downtime due to multiple outages/blips.

    I have had several APC back ups. As with the others this was easy to set up. So far it has done everything it is supposed to do. I continue to be happy with this type of product from this company.

    During a recent power outage the unit continued to supply power to the items plugged in to the outlets that support that and all were protected from power surge when the electric power was restored.

    Using this as a backup power supply for the router and wifi, easy to use and no problems so far. Hope the battery lasts longer (charge/recharge) than some other UPS that I've had in the past.

    Never been wrong with an APC UPS. This one covers a couple of small electronics that I'd like to be protected (router, modem). APC products are usually great. Does exactly what I expected it to.

    I live in an area where there are a lot of power surges so, I bought 2 of these since I got them at a great price! They have already saved my devices on several occasions. APC has the best products.

    I've been working remotely at a construction site, with generator power only and this little guy has saved me hours of work, When the generator goes down for whatever reason. It gives me enough time to save and shutdown my PC, even with the short charge times. Works like a charm!

    This battery backup is responsive and works great. It does what its supposed to do but it's only drawback is the extremely short time it provides. Good for momentary power losses though.

    I always choose APC brand UPS devices. They are built to last. When and if the day comes where you must replace the battery they are found at fairly cheap prices online.
