I can see why this product is very popular. Very simple to set-up and leave in place. I have been trying to secure another unit for my network since I purchased this one. I had previously used more sophisticated APC units, however I settled on this model so that other members of my family could manage them during an outage if I were away from my residence. Well packaged. My only comment is that the supplied software PowerPanel includes a subscription model and there was no apparent warning to this effect. Personally, I prefer that companies provide a warning so that the end user may make a choice whether to install or not.
