Since lazy seatbelts seem to be the top problem with our otherwise bulletproof T100s, Im posting this video.

Theres another video I just saw where the person soaks his belt in soapy water to remove grime and get it flexible. Not a bad idea to wash those belts.
I havent tried either yet. Ive got a misfire to diagnose but I cant wait to get these belts fixed!

Hope it helps
