I took a chance with this stem and glad I did. It’s very well made and looks great. I’m using a titanium Omni tip and the fit is perfect. Reasonably easy to clean. My only complaint is with getting the condenser o-ring in the correct position after cleaning. Now I just leave the condenser tube in the mouth piece. The stem did come with 2 extra o-rings. Very happy with this purchase and the great service I receive from VGoodiez.
