I Just bought a Grabow Royal Duke. It seems to be of decent quality. It's easy to clench. I have been satisfied through the first few smokes. I really like the price, so I can take it to work and not worry while I'm using it. On the ride home today I noticed some smoke coming from where the stem meets the wood. After taking the stem off I noticed that the metal piece that connects the stem moves around. So my questions are, why is smoke leaking? Is there a certain position the metal piece should be in when you put the pipe back together? Thanks for all the help you guys have provided.
