The old Davinci model I like the cb radio grey look, already saved my butt, with many accessories $150.00??
the newer models look like an up market phone and are often stolen
this model is easy clean and toke on re-charge, and variable temp and portable ..=all vip to me
thats ok I've spent a lot more on a bong that went thru the wash machine ..lol
re:
the unfortunate truth is vaping is a different stone/buzz/hit at least for me,
I spent all of 420 vaping as a test, and was tripping with ease come bedtime
I mistook the sucking of the whip/stem as like a sucking of the straw drinking cola etc in the theater
and easy got bombed, with no taste, smell, even flavor, and with ur attention on the action its easy to get lost
it was D Butt/ youtube that motivated me, this I need to learn and for the same reason
no one tokes weed for decades without screwing up something ...lol
after years of growing and smoking weed its very disappointing to toke on a vape with little flavor,
of which I see as a temperature related thing...for now..?
good luck
