“The cylinder is fine and the Hydrology is a great little unit. I love how modular everything is and it's quite simple to clean. The only issue I have is the rubber gaskets that seal the tube seating surface get shredded by the glass and leak. Customer support is great and has sent me new ones but they never last long. Every time you clean the unit it requires the glass tube to come out and you cut the gaskets putting it back together.”
“It is too bad the cylinder isn't thicker. Resin builds up in the tube so when you try to remove it, it is sticking to the device. I would like to add that Cloudious 9 is really the best retailer out there. Their assistance is beyond comparison.”
“I’m so clumsy that I broke my original tube the first time I washed it and dropped it in the sink and it shattered. I was wise enough to purchase this spare with my original order but this is clear my original was smoked.”
“Ive had the Hydrology 9 for a long time, and I ended up breaking it on a slip of the hand as i was cleaning the unit.
Thankfully, they sell replacements for a reasonable cost.”
