I bought the clone of this when it 1st came out for squonking and found it not so good, the cotton gets pushed out of the wick holes by the rising liquid and it will leak if over squonked and dosn't seem to wet the wickes if I try to go easy with it. I tied it with mesh into the tank and cotton on top for the coil and it was better. I was thinking of trying an all mesh wick like my gennies but haven't got around to it yet.
