If warranty proved anything, then GM products have always been superior to Honda and Toyota. Good luck getting every GM warranty honored. Dealers,. too often, get stuck with costs. So dealers will do anything to avoid honoring that warranty.
A lesson from free market economics - in numerous industries. A best warranty often indicates an inferior product. Salesmen will do anything to make a sale.
Protection for over 100 years has always been about where hundreds of thousands of joules harmlessly dissipate. Only one item has always existed in every protection 'system': earth ground. A protector is only as effective as its earth ground. A plug-in protector does not have and will not discuss that low impedance connection to earth.
Best protection (that is also a least expensive solution) is properly earthed 'whole house' protector. Then a homeowner inspects THE most critical item in that solution. Every incoming wire (TV cable, satellite dish, telephone, OTA antenna - every) must connect low impedance to single point earth ground.
That is only 'secondary' protection. An informed homeowner also inspects their 'primary' surge protection layer.
All this described previously with spec numbers. Numbers separate an informed recommendation from those who recite advertising, hearsay, and wild speculation. Who even mistakenly believe a warranty rather than specification numbers.
Protection is always about where hundreds of thousands of joules harmlessly dissipate. Then protection even from direct lightning strikes remains functional for decades. Because protection is only as effective as its only required and so essential component - earth ground. Not wall receptacle safety ground. Earth ground.
