I've done far too much research about this and the mflb is the way to go if you're looking for something to use with 3 people at a time functionally. For 100 bucks, some places 120, this thing is extremely efficient, gives a great high, and is very portable. Used correctly, this gives off very little smell, little enough to use in a semi crowded movie theater and not be caught. The gaper globe you suggested, sadly, is really not good at all. They're not portable, not nearly as efficient, and are much harder to get to an ideal vaping temperature. If being used between 1 to three people, this is the best vape on the market imo. The customer service by magic flight is amazing as well, they will warranty your vape for literally any reason for life. You break it, they replace it free. Cops take it, replaced. They're the best.
If looking for a portable thats better for more people, the iolite is good but double the price. The problem with the mflb is that people don't know how to use it correctly and don't get the high they're looking for and call it trash. The iolite is more idiot proofed but makes a hissing sound from the butane it uses every 30 seconds or so.
If you're looking for a non-portable vape, the REAL (not the knockoff ones) Easy Vape and the Da Buddha vape are both very good and around $200. You're going to get what you pay for with vaporizers with the mflb being the only exclusion that I'm sure about. There are plenty of cheap easy vape like vaporizers under 100 dollars but they're China made and let the air flow through all of the components that contain heavy metals, lead ect. I strongly advise against this.
Oh, lightbulb vapes don't work.
I'm sorry, I can't get embeds to work now.
