I am impressed by the IQ2 that I purchased last year. Easy to clean and easy to operate. I have been using vaporizers for over 10 years and have tried a few of the popular styles as they became available. My last previous unit was a temperature controlled device which was awesome with the exception of it being too bulky to take places with me as well as loading flower in and cleaning it out was a chore. Last year I saw an ad for DaVinci and had to take a peak. Compact, easy to use and adjust, super easy to clean, little pods that make it a breeze to swap out doses of flower and a case to keep the pods stored in for on the go enjoyment. I had a slight problem with the charging port and sent in a request for repair and got a response to send it in. I shipped it priority and had a new unit shipped to me within a week without any issues Customer service is awesome as is their product line. For anyone on the fence about getting any of their products, don't hesitate. Vaping flower is healthier than smoke and the flavor is like having a fresh IPA beer vs drinking a glass of bong water. If dabs are you thing then this IQ2 is for you. The health benefits of vaping versus smoke are too many to type out plus you won't smell like a stoner and no one will know. Yes, that is the Rocky Mountains behind my IQ2. A true Rocky Mountain High but Montana style. You might think these are spendy but they are so worth it.
