The pros: With the clicks you hear from those relays inside you get a heads-up on possible upcoming power outages. Otherwise in your home, workshop or office, there are no other warning signs, no lights flickers, equipment turning off, computer or audio gear malfunctions etc. They happen to fast to have any noticeable effects. But then a day or two later, a hum and the lights go out! But you had a early warning with this unit. Cons: the status LED's on the front should have a hold function because you're very seldom actually looking at the LED"s when the unit is triggered. They flash and flicker but are useless without a "hold function" or better yet ,a single LED that stays lit a while when an event occurs until you push a reset/review button. A complete LCD which can scroll through details of the events would even be better. Or how about a usb computer connection that you can review those events?
My computers, printers, networking devices, and disks became too much for my old line conditioner. I replaced it with an LC1200 and have had no problems or issues with it or the equipment it protects through several power surges and blips. That is the best praise for a line conditioner -- NOTHING happened!
I needed something to protect my musical instruments from voltage changes. This product should be the answer. What I have paid in repairs in the past, this is cheap insurance.
Once I connected to the power receptacle, the LED indicator show a fault with my power line. The fault was fixed and I sure have good and reliable output power.
