Rated 5 out of 5 by from Great ProductHad a supply voltage problem on a large (75 in Samsung 8k TV) that resulted in the TV randomly turning off. When I added this line conditioner to the input power line, all my problems were solved. I am impressed with the build quality and value of this product. Highly recommend.

Rated 5 out of 5 by from Line conditioner to use with a generatorI bought this line conditioner to use with my portable generator during power outages. The generator has sine wave output, but the voltage may vary a bit. The Tripp Lite unit will keep the voltage within acceptable limits, as well as protecting against any voltage surges.

Rated 5 out of 5 by from Another Tripp-Lite PurchaseI had an LC600 for 21+ years of dependable service... but of course nothing lasts forever. So when it gave up the ghost I purchased the slightly larger LC1200. It, too, is now working flawlessly so far and no doubt will continue to give outstanding service and reliability into the far future. Tripp-Lite products are well-engineered and seem to last a lifetime. I would always consider Tripp-Lite as a first option for power backup and line conditioning. It's an investment in protection that makes sense.

Rated 5 out of 5 by from Glad I found thisI use this to protect some cooking equipment that's hard to find.Im 50 watts under and it doesn't seem to have an issue. I don't run the full load always so its hard to say if this is ok. Most products don't say hey its actually this amount that you can use despite what they rate it at.I thought it would be bigger and I'm glad it isn't.Always not a fan of made in China/PRC.Glad it comes with an insurance guarantee for equipment. That's one of the main reasons why I also got it.

Rated 5 out of 5 by from Definitely effectiveI 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.

Rated 5 out of 5 by from Beautifully clunky, definitely usefulI use this product for my hifi setup as both line filtration and peace of mind since my equipment is pretty expensive. I used to hear line noise every once in a while, and some weird beeping. I haven't heard anything since. This thing hums for a few weeks but it gets quieter the longer it's on.

Rated 5 out of 5 by from I would buy this product again with reservations.We needed a line conditioner for our printer which was having an issue with the summer electricity brownouts, etc here in Arizona. We added the product and it helps to a certain extent. I feel safer, but I don't feel that it is 100% the solution. Our lights still flicker when the printer kicks in and when the air conditioner kicks in the printer goes off line.

Rated 5 out of 5 by from To save our sensitive electronicsAfter having issues with fluctuating voltage, this line conditioner was recommended when the Toyo boiler brain died. The unit immediately revealed a line fault and our loyal and talented electrician was able to correct the problem. We anticipate no more issues with the electronics that are plugged in to the Line Conditioner. Sturdy unit with minimum maintenance required. We are off grid with generator/inverter power system. Not sure if that nullifies the warranty. It is plugged into a house outlet, not directly into the generator. Warranty info not clear.
