The Miqro only works with ground up weed, and, I gotta say, it works real well...
It's perfect for microdosing all day long, (or getting real stoned all day long)
There is a bit of a learning curve till you get the temperatures figured out- but if
I can figure it out, anybody can figure it out.
Well made little unit, too -anodized aluminum on the outside, and a ceramic oven and air path inside-
I thought it was a good deal for the $$, and I'm
real cheap!
That's what I do too!
One thing I'd recommend, is get an extra battery or 2- the battery lasts long enough to get you real stoned,
but if someone else wants to use it after you, you've got to charge it first.
I found a great and inexpensive source for the 18350 batteries it uses-($6.00 each) I'll pm you the link
if you end up going with the DaVinci...or you can get it with the "explorers kit"-it's about 30 bucks more,
and it comes with an extra battery, among other nifty things.
I bought mine off the DaVinci website, but quite a few other vape places sell them too.
**edit.- Inhaling the vapor is better for you because you're not intaking all the (harmful) combustion by-products that are produced when the pot actually burns.
