I finally got my Mighty at the weekend and have run about 8 bowls through it so far. My initial impression is that this unit will get you medicated very quickly!
Not only is the flavor really good (which amazed me, given the plastic vapor path), but there is virtually no draw resistance and it gives thick, dense hits from 180°C. The chamber is fairly small, so you can adjust the load by grinding to varying degrees of fineness. I have found filling the chamber with a fairly coarse grind gets me nicely medicated on my own. If you grind finer and fill the chamber all the way, you should easily be able to get 3 people totally floating!
I have a fairly high tolerance and other portables always just annoyed me with their wispy vapor. This Mighty is for those that want a large concentrated dose quickly on the move.
I have also been impressed by the battery life. Yesterday evening we did 4 full bowls over a few hours and the battery still had 4 of the 6 bars. Impressive!
Although it is not quite as good as my Aromed in terms of flavour or efficiency, it does exactly what it is supposed to, while also being completely portable and boasting the best battery life I have experienced in a portable.
Ding ding, we have a winner! Now to save up for the Minivap......
