This product does exactly what was intended for me. I plug my laser printer into it and now my computer which is on the same circuit does not get turned off. It does click when engaged, however this is just a minor inconvenience as it performs perfectly otherwise.
Living in rural Florida, and having lightning storms is the norm, my apartment complex was built in the 80's so we are having power fluctuations constantly, this would effect my over the air channels reception, the edition of this equipment has helped with this issue.
Pros: Compact, Good Cord Length, Great Protection, Warranty
I hooked this up to my personal computer and my flat screen television in my guitar studio where I also have a portable air conditioner running off of the same electrical line. I live in a rather large dwelling with many units and wanted to ensure my sensitive electronics would be protected from ever changing AC voltage. The unit runs quietly and clicks periodically showing low voltage. When this happens, I know my equipment is being protected which brings peace of mind.
Pros: Compact, Good Cord Length, Great Protection, Warranty, Well Built / Quality, Well Labeled
I DJ and in one venue the electricity is questionable. My two mixers both shut down as a precaution and this was due to poor feed from the AC outlet. I now have peace of mind that this will no longer be a problem with my new TrippLite line conditioner. I use this in conjunction with a TrippLite surge protecting power strip.
