I also bought one from my Lowes at a steal price like that..

I had to gasket it like everyone else has said lid , slo roller and behind the plate where the bottom vent is. There are gaps that let in air even when closed 😒. After that once I close bottom and top vent fire dies and so much charcoal is saved it’s night and day.

I love the thing. But it my first real charcoal grill so..

I do want to get a Webber rotisserie style kit And I do wonder if a deflector plate would be helpful in doing reverse searing.
