Thanks guys,
It looks good but it's not the complete package
The main pro's to my design are the lip on the diffuser that sits on the charcoal grate
It acts as a drip tray and diffuser . Simply line it with foil and you never have to worry about drip trays again. I've been using this system for over a year and it still looks new and works like a charm
The second thing he is lacking in the design is the large charcoal basket. The main point of the charcoal basket is to keep the heat off the side of the kettle, to prevent spalling
Whether I'm using the minion method or just cooking high heat indirect
Here's a pic of the side of the basket, as you can see there's plenty of spalling and the kettle bowl that I do most of my cooking in doesn't have a mark on it
To tell you the truth I don't use the vertical diffuser that much, I find the solid wall on charcoal basket does a good job of deflecting the heat
Still not a bad design he has there, I just wish I could produce them for $50
