done correctly: surge protection is NOT a one-step process, it's multi-staged & distributed. Power company has two protectors on the service pole: an open-arc grounding point & a high voltage MOV. Inside I use whole-house gas-tube discharge arrestor, followed by MOV's paralleled across a Wattgate 381 outlet, folowed by a line conditioner w\ integral surge protection, followed by MOV's that I've instaled internal to my components.
The HG / IG / protected outlet seems very worthwhile to try out. Install one or two outlets, then after breakin you may wish to compare with some others that have been recommended. If you don't perceive any differences-to-the better, then you know you're done. If you do perceive improvements w\ another outlet then you've pretty much answered your own question.
