I just picked this and the Incendio wax pen up. I don't vape a lot of flower, but I do have the Alternate and other than the mouthpiece mine works well. I am on my first alternate mouthpiece and it is finally starting to go. If Vivant sends me another thats great, if not I'll but a crafty one. Af far as the Vleaf is concerned, I will let you all know!
