Totally agreed on the sampler selection... I bought 2 samples from vendors highly recommended on ECF - in the smallest quantities possible. I looked at the quality of the shipping, delivery time, packaging and presentation. Then, I tried each
juice out to further grade the vendor on overall quality and satisfaction.
Also, I tried a variety of PG/VG blends from 100% PG, to 50/50, 70/30, 80/20 - and a variety of nicotine levels also -
I settled in on 1 vendor (finally) after about 3 months of applied research, first hand experience, and overall satisfaction.
This is part of the experimentation phase - I think we all did this (if not subconsciously) when we tried different brands of analogs to finally arrive at our analog brand.
