Just a word of caution on this one to guys and gals who are thinking of adding a cordless drill to their Nils, etc. Home Depot ran a special last year, and likely will again, where you get a free charger and battery with the purchase of a qualified hand tool. The impression left when making the purchase is that items are eligible for an upgrade for Lifetime Service.
When I went to register all of my components, the battery and charger did not complete. I called Ridgid and was informed that the battery and charger are considered an accessory and as such, ineligible for the lifetime service agreement. I will be following back up with Home Depot because their site seemed to be misleading to that fact.
