Oh, wow. I'm sorry, I totally forgot to make note on this thread of the recent success I've had using Cignot's Basic Sweet Naked
e-liquid flavor as a replacement for ECOpure RICH. If you click on Kent C's posted link above, you'll see that I think the stuff rocks as a near ECOpure RICH replacement. I don't think it's quite as rich, but it is good enough in all other respects, including flavor and performance. Plus, it is nearly half the price of what ECOpure's e-liquids used to sell for in the U.S. Admittedly Cignot's S&H rates seem a little higher than they need to be, but are not outrageous. Large enough orders ($75+ I think) get free shipping, so I guess that's something. They are also a little slow at shipping. Delivery for me took about a week, but that's better than getting ECOpure RICH shipped from Europe.
Cignot's other Basic Tobacco flavors use only about 4% PG (Sweet Naked and their Basic Naked flavor use none), but also don't use Ethyl Maltol at all, so they simply don't compare at all in flavor. In fact, Cignot's Basic Tobacco flavors (though not bad) didn't taste particularly special to me, and are overall fairly average (or even below average) in flavor. However, they are fairly thin and do appear to run well in cartomizers without any gunk build up or coil/wick burn out issues common with many other high VG juices. Because of their flavor, I can't really recommend them. However, Cignot's Basic Sweet Naked is a whole other animal.
If you are looking for an ECOpure RICH replacement, now that it has sadly gone bye-bye from the U.S., Basic Sweet Naked is it. It has the same relative clarity (with a very slight yellowish tinge), is functionally thin, runs clean, and has the right flavor and vape impact. I don't really know what else to say about it. There may be some other VG e-liquids out there that are nearly as good a copy of ECOpure RICH (or even better?), but I have yet to come across one. Give it a try. I'd like to read what other forum members think about this
juice, and how close a match they think it is.
