Stanthemanchan, you were right, the hole is off-center! Got my Rose clone today (from e-cloudvapes) and right away, I had problems. The o-ring in the top cap was too big and already shredded and the o-ring below the AFC ring was torn. I was able to replace both o-rings from my growing collection of parts and finally got it working, but it wasn't easy. I feel the top cap hole should have been chamfered to prevent the sharp edge from cutting the o-ring. Also the chimney threads were very rough, making it hard to screw on without cross threading.
For less than $40 and a little work, I have a usable Rose, so I'm somewhat satisfied. But I think that someone using the Rose for the first time would have regretted buying this clone.
I had the same torn o ring at the top of the chimney. My threads were crunchy, too, and now they are working pretty well. And the afc is finally spinning freely.
