I've been able to partake in a few Davi No. 1s that have all been amazing, that being said I have heard from some good friends that they are really hit and miss, some of them are flat and some have construction issues "welcome to the world of a handmade product" as Carl said, I have purchased and smoked 2 Davi 5000s and they were freaking amazing to me, never tried the Tubos, but that will change soon, a trusted source of information has told me the tubos are outstanding and he's never had a dud in years of smoking Davis, that made me feel better after hearing all of the horror stories about he No 1s LOL
I will probably smoke the first Davi No.1 at our weekly Thursday night herf here in SD, a little puff puff pass action.
