I would give 4.5 stars if I could.  It's still early but the grill seems great.  I just wish there was more "how to" instruction to use certain functions.  Either in video form on your website or in the instruction manual.  It would be nice to be able to read/learn the best way to use the Manual Function of 1-10 settings and the SmokeBoost feature.  I found the fifteen second videos on how to set them, but it would be great to have advice on the best way to use them.
