I love the IQ2. It has a huge varity of settings to make your hit just the way you like it. My favorite is at 419 degrees with a bubbler attachment. I also enjoy 390 degrees with the air intake set at 3 and cinnamon apple herb tea in the flavor enhancer on a fresh bowl of OG Kush. Try it out. You can't go wrong.
I've been playing with it for about 10 days. Four stars because of Apple and not distributing the software. Instructions are good if you look for them on Youtube. I cannot use the built in dosage meter, although I pretend, because I don't have access to products that have been tested for THC/CBD levels. I can't even tell you what I'm smoking. Sad but true.
The taste grows on you. Nice and toasty. I like to start with two level two sessions in the morning kicking it up to level three for the next two. (Don't forget to check THC/CBD after each session, if you're into that.) I'll finish off with one, hoping for two level four sessions. I try to do four twelve second inhalations per session (The DaVinci has a 12 second timer, if you use it right.). If that doesn't finish my day, plug her in and do it again. The battery seems to last pretty well but I turn it off (Five taps on the button) and save it rather than have it automatically turn off.
In itself, the DaVinci is,like I said, it's a nice and fun little gadget. What clinches it for me is the glass extension you can buy so you can use it in your bong or waterpipe. SMOOOOTH!!
Apple screwed this Lil' Darlin up.
