When I first started doing tumblers I used a convection oven and would have so much ghosting and burning. I wasted over 25 cups, got so frustrated that I almost quit. I got a message from Veronica and she lifted my spirits and I ordered their press. Let me tell you I literally cried pulling the first tumbler out and it was perfect. I haven't looked back since, so if you are hesitant don't be, just do it!
