Hi! Long time lurker as I didn't have anything of value to contribute since I'm a newbie starting to learn about the different Nicotines and DIY.
I just received a sample from NN and I didn't care for it. To me it has a pretty strong fishy, "weird" taste without much of a TH that I could tell. Though the scent was very mild. FWIW, I mixed it at 10% and I normally vape 3% Nic.
I should add that I have a very strong sense of smell ever since I quit smoking 2 and half years ago. The way I'm able to detect mild scents from far away is uncanny. Still blows me away as I thought I'd grow accustomed to it after awhile but not so. So, since I think NN's is a mild scent than it must be which makes the odd flavor all the more...odd.
I've only tried one other Nic., from One Stop DIY. I love it for an unflavored Nic. It has no odor and no flavor. I've had it for over a year and and a half, kept it in the freezer and then in the frig and then on the countertop for over 6 months in hopes of creating more flavor and it still tastes/smells completely flavorless!
I'd love a Nic with tobacco flavor and a lot of TH but if I can't get that I'd rather go for the one most like OSDIY or no flavor/scent rather than NN any day. To that end does anyone know what OSDIY sells?
I also have some ECX which I hope to try ASAP and will report back when that happens.
Thanks so much to all who've contributed to this thread over the years. I've read a lot and learned a lot and also confused myself in the process.

But, hey that's the way I do things! I love to research and analyze everything to death!
Cheers!
