I've tried Mango Martini from DFW Vapor and Mango Ice from Vape Dudes.
Mango Martini definitely has some sort of alcohol flavor that adds to the throat hit. The mango flavor is very nice but I have a difficult time vaping this for longer periods of time. It just seems a bit harsher that what a mango should be.
Mango Ice has a very nice, strong Mango flavor with a pretty decent menthol. I actually like a bit 'cooler' menthol but there is nothing wrong with the mango side of things.
