I'm looking to add a surge protector to the 100 amp sub-panel in my shop, primarily to protect the electronics in my Powermatic 3520 lathe (3-phase inverter).
A friend recommended this gizmo from Square-D:

It's about $25 on Amazon and seems priced significantly less than similar "whole house" surge protection devices. Looks easy enough to install and, bearing the Square-D name, I trust that it works as advertised.
Anyone here have experience with this surge protector or similar devices? Recommendations for or against?
