I have one on the back porch and it really lives up to it's name if left for too long. I try to empty it at about the halfway point but that rarely happens. I really like how it's deep and ashes don't blow around with these Texas winds. Get one, you won't regret it.
The Stinky Ashtray comes highly recommended by the DogWatch boys, and that is good enough for me. I have not purchased one - shipping would be horrendous to Canada, but since I smoke outside I have a huge backyard for an ashtray. LOLOL
