Hubby bought me the 3 pack bundle and all I can say is OMG!!! I love the hydrology 9, super cute, perfect size, a little hard to hit (but that could just be where I’m not used to it yet). The atomic 9 is the PERFECT discreet, almost palm size, dry herb Vape. They’re both super easy to use and to take apart and clean. The tectonic 9 grinder is cool for the simple reason of the dispensers and vibration aspect. I personally think the grinder is somewhat lacking it would be better if the grinding teeth were metal instead of plastic and if it had a Keif catch, but overall it’s a cool piece to own. Their customer service is AMAZING!! Super courteous, fast, reliable, friendly, and helpful. Would recommend Cloudious 9 and their family of products to anyone who’ll listen! BOTH vaporizers are worth the investment!!
