I decided on the MFLB. For my purposes I need a portable. I was sure about the DaVinci but I read many bad reviews. I was thinking about the Vapir2 but the look of it was the problem. The other choice was the Arizer solo but from what I read its too bulky.. It sure would be nice to go into a Target store and see them all, ha maybe even demo some Cannabis vapo. I like the vapo quality very much, I am still getting the hang but its such a sweet adventure. I had thought that the MFLB was filled with hassles and learning curves, I can say with clarity that it is very easy to just start vaping quality vapo. The main hassle for me and this leads me to my topic is what would your ideal vaporizer - portable look and work. For me the look of the Davince and work like the MFLB but the battery is attached inside, you flick a button once and the action starts... The main draw back on the MFLB is the stem is not attached and its a bit potential for fragility so u have to keep aware of it. if only that stem could be attached to the main unit. the battery part is also a shame its not attached but I get the MFLB, it does a fantastic job producing the vape. It is my feeling strongly that we will see more and more vaporizers of all sizes coming to market this year. Such that the price I paid on Ebay for this was pretty cheap. $75 (but with a kind of limited warranty) but i will jump on some new vapo if that new one will attract me with all the qualities I seek, this one I wanted to see for myself, the MFLB is a legend no doubt.
