I spent a weekend with mine and in my experience, its quite easy not to combust, especially if you're used to the MFLB. My issues with the product is that I don't see a real place for this if you already own a MFLB. I'm quite a fan of the company and it's products.. maybe even considered a fanboy (I'm one of those who actually sold off high tech vapes costing triple the MFLB because the MFLB was still just a better fit for me), but this is probably the first product from MF that I'm not wild about. It looks great, the size is tiny for sure.. but my main thing is that it compromises too much to not have any real advantages over the Magic Flight or many other smaller vapes out there. It takes more effort to use and because you have to deal with the short-comings of the unit, I find it actually less stealthy than the Launch Box... but maybe that's more of a testament of the Box's design because it was already small enough to begin with to never be a real hindrance. The biggest weak spot of the unit is the metal lid. It's quite fragile feeling and doesn't lock into place. I would not feel comfortable loading up a trench and keeping this thing in my pocket... so the fact that you'll most likely have to carry additional herbs with you just to take a hit makes it less handy than the LB. Also, I tested out about 7 batteries and only 3 worked with it (2 were Amazon Basics, 3 were silver Glyphs and 2 were the gold ones that came with the unit.. all of these worked in my other Boxes and Maud Dibs). On that note, the battery life does seem quite good so price and battery life might be the only advantage it has over the Box.
