The Brick is sold at a great price and it does the trick, but it does not want to stay stuck on my humidor lid. It came with a thin metal slab that is supposed to stick to the humidor (I placed it on the lid), but it falls after a few hours. I keep having to restick it. Then, the magnetic slab that is glued to the Brick would detach from the Brick and I would have to reattach the magnetic slab to the Brick.... I know it was only 9 bucks, but it's getting old! I'm afraid to purchase glue to fix the issues here, but I don't want glue fumes in my humidor. I'll live with it unless you guys have any suggestions.
