I have been using the IQ series for a number of years and although I’ve tried and bought others dry herb vapes. This by far is the best for price, quality of vape and most importantly a good customer service experience… and let’s be fair not many companies can say that! The only problem is the build quality can be almost timed for when the device will not function properly. I’ve run into many different problems and issues with almost all my da Vinci iq products but it’s still the coolest looking and the best for flavour on the market. My only suggestion is stop trying to get the software to be to clever and get the hardware and the software to be at the same level please also try to solve the ‘devils anus’ under the flavour chamber easier to clean. I hope this helps
