I ordered two APC LE1200 Voltage Regulators to use on two of my TV/entainment centers in the house. It is money well spent for the peace of mind. In my locale, power is on & off frequently along with dips in voltage. APC offers one of the finest groups of electronic protection equipment that I have found. This unit is no exception. It is well designed and rugged looking. Both worked right out of the box and I expect no problems with their operation in the years to come. The second reason to buy such a unit is if you have a portable gas-powered electric generator that you use for temporary power outages in your area. Many generators do not deliver the perfect power, which is clean and well regulated, to meet the strick requirements for many of the home entertainment components. This unit regulates the power at your equipment and "cleans up" voltage & noise variances which may come from the portable generator.
