I have also been on the quest for a good donut vape for the past several months. I have tried several and well, the search is still on. Below are my flavor thoughts based solely on my honest opinion. Perhaps I can save a few members a few $'s based on my opinion.
Namberjuice Donut Pounder: I thought it was pretty decent fresh BUT, after about 1.5 months of steeping in a dark, cool desk drawer, it developed a very unpleasant, artificial plastic aftertaste. Down the drain went about 20ml's.
MF'N Donut Original: Chalky chocolate taste throughout the entire vape.
MF'N Donut Glazed: Same thing, chalky and incredibly artificially sweet on the exhale.
Coval Vapes Chocolate Donut: Another muted, chalky chocolate IMO.
Coval Vapes Churro: Not really a donut but close enough I guess. This one was decent but slightly muted. My taste buds kept wishing for more flavor.
VW TMAXX Blueberry Donut: Received this one extremely fresh and it needs steeping time. It was not very good fresh.
VW TMAXX Lemon Filled Donut: Same as the TMAXX Blueberry mentioned above.
I Love Donuts by MadHatter: I haven't tried this one because the majority of member feedback has not been good, and mirror that of the OPs.
Velvet Cloud Vapor's Night Shift: This is a max VG flavor blend of chocolate donut and sweetened coffee. The blend is very smooth and the coffee element is just the way I like to drink my coffee. This is a reorder for me, and the max VG makes for a good juice for dripping.
The following are on my list to sample in the future:
Alt Cig's Dunkin Doodle
OneUp Vapor's Churro and Ice Cream
Nola Vape's Beignet
Any feedback on the above would be appreciated.
