Simple to prepare, charge, rack and use, we have several Tripp Lite UPS in our small data center. We have experienced very few failures in 4 years. The devices provide a good LCD read-out and good network diagnostics. The rebate capability is excellent, which means we will stick with Tripp Lite long into the future.
We bought two units for our office to install in server's rack. Installation, setup and use was easy and intuitive. Lots of features and very informative display. Both units work fine and no problems at all for almost a year already. Pros: good price, time on battery, features, display, easy installation, rack-mountable Cons: none
Have a few of these in my MDF and IDFs. Tripp Lite is my goto company now. I have a set of these backing up my two HP servers running all of my VMware virtual servers with failover setup.
I am a scientist, not an IT professional. I use this UPS for a small deployment of storage servers in my lab. It has more than enough capacity to keep multiple Dell Poweredge R510s online until backup generators come online. It was easy to set up -- I did it myself--, features a large, easy to read and understand display, and is of high quality. The fan is a little bit more rizzzzzy sounding than I would prefer, but the server rack is in a corner and it does not bother us. I would highly recommend this UPS.
