I've been using a DaVinci IQ2 for a while and really like it. I'm a pretty light user, I just vape one time a day an hour or two before going to bed, gives me some time to relax and helps me fall asleep. Anyways, the thing I like about the IQ2 the most is their stainless dosage pods. They only hold like 0.3g but that's enough for a vape session. And they have an ingenious grinder that you easily pack a 6-pack of pods super easy, and a storage holder for them that's pretty nice and helps with smell. It makes it so easy to prep for a few sessions and minimizes cleanup by quite a lot. And with their app you can set up your vape and even put in your strain info to track THC consumption, if that's something you want to do. Downside is their ecosystem is pretty pricey, but they have been including their pods or a grinder lately.
Overall if you're not a heavy smoker DaVinci makes some really good stuff. It gets pretty hot so I'd recommend getting their silicone glove and giving it some time to cool off between sessions. Gotta look around for coupons, though. MSRP is like $299 for the IQ2, but I think I got mine around $230. IQC is a bit cheaper, I have one as a backup just in case, really just the mouthpiece and some app functionality are what you're giving up. Plus the IQ2 has a 10 year warranty and thr IQC I think it's like 3 or 5 years.
