We used to sell a lot of these to a couple of our regular clients. These are a great size/function/cost combo for someone with a typical office desktop setup - PC, couple of monitors, desktop printer, etc. Small enough to keep relatively hidden under a desk but will provide more features and (potential) longer run-time that the smaller, cheaper options that APC sells. Recommend.
First one lasted more than 10 years, finally got a little weak this month (September 2019). It was connected and protecting our computers and hard drives 24/7! Almost forgot we had it... 11 trouble-free years! You can't ask for more than what this BK350 gave us. All pros, no cons.
Pros: Ease of Management, High Quality, High Confidence Level in 24/7 Uptime
