I've been assuming all along that there wouldn't really be any warranty recourse on these coop units, because typically the warranty would be handled by the vendor rather than the manufacturer. if you are looking at 70% off the price of a kit, that's a chance I'm willing to assume. Use it till it's dead, then dispose of properly. I was thinking if people involved in this were concerned about a warranty, then they should buy 2. That way you have a replacement if one is DOA.
I'm still in for at least one red or black 18650. It's a great deal, but I still am saving for a Root Beer Buzz Pro because I think it's a better device for me, but for 30 bucks plus shipping and a couple other small fees for a kit, it's a GREAT deal. It's like basically buying 2-18650's and a charger (assuming that's what comes with kit), and getting a LT for like 5 or 6 bucks. If the LT is dead, or lives a short life so what.
