I had some Simrell Stems lying around and decided I wanted to use them for my Enano XL. Cue Simrell, who has manufactured a chamber that allows me to use my stems with my Enano XL. The fit is perfectly machined. I can put the Extraction Chamber on the XL and get a hit right away, or I can let it sit there for a little bit and heat up the Titanium walls of the Extraction Chamber for a nice added conduction to my inhale.
