Don't know about their quality, but it's the right way to do it.

The ONLY safe place for MOV protection is at the service entrance
-- the "whole house protector." The only safe protection on a
branch circuit (that is, anywhere else) is a SERIES MODE
protector. Series-mode protectors store the surge in a big
inductor, then slowly discharge them after the surge has ended.
They are widely used in pro audio systems, which have many
interconnections between equipment. That industry uses protectors
made by Surge-X; a company called Brick Wall is a competitor that
focuses on the home entertainment market. I use Surge-X units in
by home, office, and ham station.
What about Zerosurge? They look to be the same technology, but cheaper.
