The Hydro is the most versatile TED I've ever owned. First off, I only use Induction Heating, not a Butane Torch. Not only does the Hydro elevate the one-hit extraction slightly above the Classic Simrell Titanium, but it takes the Vortex cooling stem to a whole new level. After one month of intense usage, I have switched the Hydro Heat Exchanger assembly to be used on my Simrell Titanium Vortex Stem and put the Simrell Titanium Heat Exchanger assembly on the Hydro Chamber/WPA. For my usage, they both seem to perform better when switched. I have literally sold all of my other TED after experiencing the perfection that is Simrell.
