Summary: So far I am very pleased with the product. I am concerned with with condition of my power because anytime the power goes out at our home, I have startup issues with my computer. I recently got an expensive computer and do not want any difficulties with the power. I am glad I read the reviews because of the picture on the description. It looks like you are getting a two piece product but that is two conditioners stacked to show the front and back.
Summary: Had an issue with overvoltage that my utility company didn't want to fix. Fried a $400 home theater amplifier and had numerous other issues with sensitive expensive electronic equipment. Plug this baby in, set it to regulate to 110V and have not had a single issue since then. Cost is nominal for protecting $2500 worth of electronics. If I could give it ten starts I would!
Summary: This product is basically a box of wire with some lights on the front. I purchased this product to go between the wall and my UPS in order to provide constant line voltage when running on a backup generator. The issue was that my UPS was blocking its outlets when the incoming voltage was too high. The issue with this product is that it only regulates the voltage up or down when the voltage is out by either 6 volts or 6 % (I cannot remember which).
Summary: this product was simple to set up, did exactly what I wanted it to. And hopefully will give me many years of protection. I have a high end piece of audio equipment that was tripping ofline for an unknown reason. the manufactur informed me that there was most likely a over voltage situation. Sure enough after plugging this device in, the lights indicated exactly that, and now the sound system is working flawlessly.
Summary: I do audio/visual presentation professionally and we had some trouble at certain venues with line voltage drops. Video switching equipment is very sensitive to line voltage variances and this piece worked great to solve that problem. Good quality.
