I waited a month before giving my input. Upon receiving this pipe , I checked the craftmanship, very nice.. I was looking for one to replace my 40yr. old pipe that also had a cover . So the first thing I did was loosen the cover w/ an allen wrench, so as to give it more play. A tip for everyone the cover saves the product from burning off so close it after every toke, also you want to clean not only the pipe but take a razor blade to the bottom of the cover as you will notice that it gets a little tougher to close after a month or so of use. so scrape the bottom and your pipe will last a long time. I give this pipe 5 stars. John
