Wings look good, but back to your question. I don't have a Vortex and I don't think it is all its cracked up to be. I did a rotisserie chicken last night with the weber charcoal holders and the temp was 450 F,,,,and that was with Kingsford Charcoal. I don't believe that exspensive item is going to make my wingas better
Some people fall victim to sales pitches and believe it,,,,,,,I for one say its not needed
