Great solution for older houses

DANIEL July 6, 2020

This is a well thought out product and easy to install. I have an older home that has the old metal wall switch boxes I tried installing a competitors version of AC switch unfortunately it was a tight fit and the electrical screws in the back made contact with the metal part of the wall box, you guessed it... instant fire. This unit was a natural solution to the problem I was having I liked it so well I ordered two more for other places at our house. Very pleased with this product and the quality of the build. Take this from someone who never writes reviews on anything. It's great!

Works Great, Bright Green Light

April August 7, 2025

Everything seems to be in working order. Very easy to use. I like that it's smaller than traditional surge protectors. No complaints on its operation, function, or form. However, the green light to indicate it's on and working is very bright. So much that the light from it seeps into my bedroom adjacent to the office where this is used.

Travel charging. Compact and well regarded surge

anonymous August 22, 2025

Meant for travel. A well regarded device at a very affordable price. Compact. I suggest buying 3-4 and placing it strategically so that there are lots of options for worry-free charging.

Good with limitations

David March 31, 2025

The surge protector covers the wall. plate. So if you have two outlets, it will cover one. The protector's outlets are close together so if your device has a transformer or wider plug, your plug will cover the remaining outlets. The protector's plug does not fold down like others of this brand, so when traveling they will stick out.
