It provides 1045 joules maximum protection, with 3 line AC protection, and has a built in phone splitter. LEDs show when the outlet is grounded and protected. They offer a lifetime warranty of $50,000 for connected equipment warranty if the surge protector fails, although what you are going to be attaching to a single outlet worth that sort of money does puzzle me. It has 45,000 - max spike amp.
User reviews were extremely positive, one user saying it protected his phone and modem against a direct lightening strike. They said it was solidly built, and came with good directions. One user did point out that the fine print says that if a device such as a TV does not also have protection for the cable, the warranty is void. The single outlets are very handy for home theaters as you so not need long electrical connections to the main surge protector unit. Note that these are 120 volt devices and are not meant for travel to countries where 220 is the norm.
