Today I noticed my light didn't work before a dive, so I messaged AG and told him about the problem. I dropped by the shop, and the second I walked in he and his people tested all the leads of my light including the charger to identify the problem. They replaced out the charger and batteries inside of the canister, free of charge. In fact, they even cleaned the leads on the E/O cord connector for me 
(I had a backup light that's as bright as the canlight, so it all worked out well.)
