Query: Had more features than other brands

I purchased this UPS for my desktop computer. I have no available USB ports on my computer, so I was really concerned about where I would plug in a UPS to enable automatic shutdown. I started looking around online and found that Cyberpower included serial connectors on their UPS models. This was perfect because my computer had the available serial port. It's actually nice to be able to put that port to use, because otherwise I would never use that port. I don't know why other brands don't include a serial connector as well. The only small negative, is that Cyberpower does not include a serial cable! So I had to purchase one of those separately. Everything was easy to use and install. I've had no problems with it. I feel protected from surges and power failures. I would recommend the product!
