I purchased my Da Vinci IQ just over a week ago, so I'm still in the honey moon phase but I can say I'm very impressed with this slick little device.
Love the athestics, surprised how small the unit is, with the original mouthpiece it can be completely concealed in your palm on the go, although I personally prefer the 10mm water adaptor as a mouthpiece.
Changeable batteries is also a massive win for me, I have 6 spare so that should keep me busy
I haven't quite worked out the battery life yet, but I think so far I've been getting about 3 10 minute back to back sessions per battery.
I'm overall very impressed with the function of this device, the flavour is exceptional for a conduction vape imo. I consider it a very pure vapor, as there is no charring or popcorn flavour there that I get from other conduction units, so a bowl will finish a bit quicker than my other units, but imo from a health perspective is a huge bonus, if you're looking for completely cashing your bowl to near combustion it's maybe not so appealing.
The vapor quality is still smooth on higher temperatures, and very tasty. The flavour chamber definately acts as a cooling system much like the Mighty/Crafty mouthpiece imo. So in that respect it's great, however I don't intend to ever really use it for other herbs personally.
The App works smoothly running on Android, I like the detail on it, but it's great to be able to use the smart path system without the app too. I prefer precision mode personally but it has been a nice change doing Smart path sessions that are a bit more drawn out, it really does slowly build up and works well IME.
One drawback for me so far is the bowl is a bit larger than i'm used to, and I can easily fit .3 in there at least IME, it still vapes well with less but there is a significant difference if you really pack and squash it down, the airflow is still good. I have the glass spacers on the way from Da Vinci so hoping they do the trick.
Another downside for me is the unit does build up oil very quickly, and being a bit of a vape clean freak, I've already cleaned the unit 4 times. It's not too tricky to clean apart from getting to the bottom of the bowl, and there's a bit in the flavour chamber that is a bit hard to reach, but with some extra long Q tips/cotton buds with a little ISO does the trick, it's just a lot more maintanance than I'm used to.
The unit also gets almost too hot to hold after back to back sessions, and the battery gets quite hot too which is a shame. Apart from that I am in love with this unit, so stealthy, incredible flavour & a cloud machine. I am a total fuss pot too btw I'm actually very happy with this purchase *Raises IQ*
