Short and sweet summary as called out by Gamers Nexus:

1. Testing methodology sux and results are not sanity checked, thereby misleading consumers.
2. If errors are caught, they are corrected poorly and acknowledged with asterisks or in description, which does not put enough of a spotlight on it.
3. Trashing on a small company (billet labs) that makes dope coolers for performing poorly due to improper testing and not retesting because "I don't wanna spend 500 bucks"
4. Not returning the prototype which was sent to them by billet labs for testing and AUCTIONING IT OFF (allegedly to a potential competitor) at LTX.

You can watch the Gamers Nexus video on the LMG for context. Steve highlights a lot of errors that they've made.
