The HOOB mars is the best pipe I own. I can definitely tell the difference between having and not using the diffuser. The purge system is solid. It is a sturdy and good looking pipe. It sits pretty high on my bar. After my first couple of smokes, I dropped it down to the mini mode. That’s probably where I’ll keep it for the most part. The draw is nice, not too restricting, more of a medium flow. I know that I have to clean it regularly, just like any other pipe. But this pipe has magnets in the hose attachment that I have to make sure don’t get rusted. There is a back up magnet and purge ball in the box. I bought a LED light for the hookah. It was not included in my purchase.
