Rated 5 out of 5 by from Excellent ProductWe installed 5 of these about a month ago. We had a power outage on 10 June 2010 and they worked exactly like they were supposed to. Very smooth transfer to the APC, just as smooth when power came back on in 10 minutes. We are very happy to have installed these before our usual round of power outages, they usually occur once every week or so. Keep up the good work.

Rated 5 out of 5 by from Works as PromissedI bought this for my daughters desktop because her last one was damaged when the power went off several times which happens in our area. This has helped save the computer many times.

Rated 5 out of 5 by from Great Product but have some concernsI have purchased BK350s in the past and have had great success with them in helping me to protect my equipment. However, I am presently having difficulty installing the software for auto shut down. I understood that the new software would work with Macs.

Rated 5 out of 5 by from Adequate but expensiveI assume this product will work well when needed. APC products generally do. However, I have 1 gripe and 1 kudo.Good: a paper with the model & serial numbers is taped to the side of the unit. This is handy for registration. Avoids need to remove plugs to read sticker.Bad: despite bragging that they have room for 2 transformer plugs, they do not. At least not if one is a 2 blade style. Mine covers other plugs.
