A lifetime warranty is a very
Surge protectors have a limited lifespan, measured in joules (a joule is one watt-second). A surge protector rated for 1000 joules (for example) can survive ten 100-joule power surges, or two 500-joule surges, or one 1000-joule surge— and then it's nothing more than a very short but very expensive extension cord.
You will never know how many joules of energy there are in a single power surge, so some "authorities" on the subject will tell you to replace your surge protector after every surge. That gets prohibitively expensive very quickly. That's where the lifetime warranty comes in handy. With the lifetime warranty, you're not really paying for one surge protector, you're paying for a lifetime supply of surge protectors. But even so, get the surge protector with the highest rating in joules that you can afford. Because like I said, you will never know how big the surge will be.
For the record, a Progressive SSP-30 is rated for 1825 joules. A TRC surge protector is only rated for 1020 joules.
