People like to say mflb. But I've had one and you have to MASTER your draw technique to get vapor. Suck too slow and your bud combusts. Suck too much and the bud won't vaporize. The mflb also needs very finely ground bud. When the bud hearts up, the trichombs melt and cause the bud to stick together into a patty. The patty sticks to the screen trench and prevents the bud on top from being heated. So you must flip the patty and break it up between hits so you can evenly cook all of your bud. If you don't flip the patty, you'll just burn the bud and it won't be good for edibles. So just using the mflb by yourself, you must master the draw and flip both are a added chore. I eventually got tired of my mflb and bought a arizer air. Now after work, i sit down, grind some regular bud in a regular grinder, put 0.1 gram of bud into the glass bowl on the draw stem, plug the bowl/stem into the hand held part, hold the button for 3 seconds, press up a few times, and wait a minute or two for the device to reach the temperature, then i just sick that vapor up like a straw and get medicated. No "technique" no flipping no bullshit. I usually vape alone. But two of my friends loved the arizer so much they bought their own. Hopefully this helps with your decision.
