My Davinci arrived today, and came off the charger a half hour ago. Thanks for the fast shipping Karma! I'll try to get some pictures up later or tomorrow. For now, some first impressions.
SOLID CONSTRUCTION:
You can't tell from the pictures, but this thing is very well made. The buttons and switch are strong, with no wiggle. I expect they will hold up well to heavy use. The plastic is thick and solid, like a Pelican case. I doubt you'd break it open if accidentally dropped. The charger is also heavy and solid - not a "cheapy".
Nice presentation too. You get a metal cookie tin box with two foam/velvet trays that hold the unit and charger.
DESIGN:
They did think quite a bit about the layout of this. There is a tiny brush that has a holder inside the lid. There is also a small compartment you can store your materials in for later use. There is a pop-off lid to it.
You have an upper and lower chamber for plant material, basically. There is a small oil-can for concentrates. It doesn't hold much, but if you maxed out both chambers I think you'd get a small J's worth; maybe 1.5-2 solo stems is my guess.
FUNCTION:
It heats up FAST. You can watch it on the LCD - about twice the speed of my Volcano. It produces decent vapor. I haven't packet it full yet. The ABV is very evenly browned though. So far, with a couple of bowls, not a single black spec. Zero combustion.
Only CONS so far:
1) Even when you unscrew the whip, you can't open the top all the way. You don't have a straight shot into the lower chamber, so cleaning that may take a little creativity; maybe a bent Q-Tip.
2) The oil can has a plastic or teflon lid (some type of heat resistant, I'm sure, plastic). I prefer all metal in the vapor path, especially something that drops right above the heater, but not a deal-breaker. I'm sure its safe at the temps used.
3) There is a definite smell and taste of rubber or plastic. It gets into the taste of my SourD. It's a little off-putting. But the device is new. I'm going to run the battery through a couple of cycles at high heat to see if I can work it out. It doesn't smell nearly as much when cold, so the heat is definitely kicking something off. Even my Plenty has a little smell though.. I'm not going to jump the gun and get worried yet. Its probably just normal...?
All in all, I am very impressed. This is a SOLID unit. Nice design. Good function.. Excellent work for your first herbal vaporizer.
