I have a Ridgid cordless drill and impact driver, but not the brushless. It has been really good and I have had them 2-3 years. I also have a couple of their corded saws and they have been good too.
They do make it a pain to register, but so far I have got the registration on everything I have submitted. You have to do each part separately, each tool, each battery, the charger, etc. Also, if you have them replace something you have 90 days to re-register the new serial number; the old registration does not carry through to the new item. I have had a couple of times when I did not get the confirmation back in a reasonable amount of time, like 8-9 weeks, so I mark may calendar and at about 80 days I send them an email and tell them I am going to return the tool to the store under the 90 day return policy if I don't get my registration before the 90 day required period and so far that has worked. I figure if they aren't going to get the warranty registration back in time, I will swap the tools every 90 days until the live up to their end of the deal.
