Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    I bought this UPS back up supply to keep my cable modem active during a power outage. I recently had a power outage and it kept the cable modem up for two hours. It worked well.

    Performance has been solid. This was able to run a monitor, laptop and peripherals for around 20 mins. Bought during the daily deal and got it on sale. haven't used the ethernet ports but I assume they are good as the others. This can also stand on its side which helps with placement.

    Is able to run both my PCs after power outtage and give me plenty of time to shut them down. If you have any type of valuable desktop, it’s worth the investment to protect.

    Bought this as a battery backup for my wireless internet. I have had 5 power outages since then and it has kept everything up and running! Great product and its unique shape was perfect for fitting in a tight spot where my wifi is located.

    Does the job, protects your equipment while providing battery backup. Saw this in action when our power went out and was still able to save my files and SHUT DOWN SAFELY.

    After a knee replacement, we needed the comfort of knowing that my wife would not be stuck in the power recliner if the power went out. It worked great.

    I bought this to reliably keep a lighting control PC up and running. This battery backup keeps a clean solid electrical signal and keeps the lights on whenever I need them.
