I have never had a better vaping experience than when I use my Hydrology9 vaporizer. I vape every evening to manage my chronic, unrelenting pain caused by a handful of autoimmune disorders, and the hit is always so smooth and potent. I have never achieved the same benefits with any other vape or pen. I also want to commend Cloudious 9 as a whole; their customer service is unparalleled. My vaporizer began chipping slightly on the glass cylinder and all I had to do was contact them, explain the situation via email, send them a few specs and they happily replaced the affected components. It was extremely painless, and they were very friendly. I really can't say enough good things about this company and their exceptional product.
