Everyone says the MFLB is smaller when they see it in real life, so I was prepared for it being small, but I still thought "Wow, smaller than I expected". The small size of this box is its real beauty! It is built better than I expected. From all the dozens of pictures and videos I have seen about the MFLB, it is totally different when you see it for real.
I might as well share what I never knew... the screen (trench/trough) doesn't actually touch the bottom of the box, it is suspended, this allows the vapor to be drawn from below the screen. The design is ingenious because even if you shake the material around, the way the box is designed all of the material is always touching the screen.
Despite my initial worries about this using batteries up fast, it really doesn't. One battery will probably burn about 4/5/6 trenches and in that time, the other battery is charged... hours ago.
Even though this includes a charger (with UK adapter which is vital if you're in the UK), I also ordered the Powerex C9000 charger and 4 Powerex 2700mAh batteries, it will be nice to have 4 charged batteries for a day out. Maybe the 4 could even last you 2 days, but this is a solo device really, if used by just one person then you probably won't have to worry about batteries as long as you always put the dead battery on charge as soon as you see the indicator light go off in the box.
Because you're discharging the battery 100% in the MFLB, when you charge back up, it will be a decent charge (unlike some electrical devices that would say "low battery" and leave some charge in but refusing to switch on etc).
If you are thinking about getting ANY vaporizer and don't own the MFLB, it is well worth getting one. Don't forget, this is a hand made item, if it becomes extremely popular then who knows, maybe there will be a shortage! At this price you would have to be crazy not to buy the Magic Flight Launch Box. As for how efficient this thing is - it is very efficient. I seem to only use about half yes half the material compared to smoking it.
