Don't buy this, since the manufacturer will not stand behind their product and will lead you to believe they will stand behind their warrantee - they will NOT.These products do not perform as advertised - your connected equipment will get destroyed -...

We have several of these in our office, and after less than six months' use, the back-up outlets in five of them quit. The surge outlets still work, but the back-up ones don't, which makes them completely useless for PCs.
