Review on 🔌 Powerful Silver Panamax M4-EX: 4 AC Outlet Surge Protection for Ultimate Safety by Jim Booth

Not too different from other line filters. Very simple functionality. Generous protection for devices connected to the device. One feature I really appreciate is the voltage regulation feature. If your home's electrical grounding is suboptimal and some of your wires in your electric meter are fraying like I did, you may have suboptimal voltage that can destroy electrical equipment. It can detect low voltage (like mine), warn me and turn off my devices to avoid damage. A standard power strip will just let your stuff die of low voltage, and you never know something's wrong until things go bad. Then it's probably too late. I think this or a similar voltage regulating/sensing surge protector is worth the extra $20 it's worth depending on how well you hook things up.
