I bought a Ridgid cordless set (the big $550 one) and sent off all the paperwork for my Lifetime Service Agreement. It took about 10 weeks and now Ridgid's website shows all of my tools with serial #'s as being covered. Home Depot even swaps batteries with you right at their store so no waiting for them to be sent off and repaired. Anyone ever deal with replacing a battery or tool? Seems like an unbeatable deal...
