I also received the Duff's airbrush at Christmas last year and I love it! I have had no problems with it and have done several cakes with it. I thought is was pricey and at the time, they would not allow you to use coupons on Duff's stuff. I am a hobby baker for friends and family and would purchase this again. But I also have had some issues with some of the gel colors. I will try the vodka to thin it out and see how that works.
