I received my Rath Waffle Juice yesterday from litecigusa.com (a day later than expected, thanks to the USPS). Incidentally, it is also my first VG juice, so I thought I would relate my thoughts.
I'm vaping out of a Joye 510, and I usually prefer the lighter, fruitier PG juices. Waffle is really great! The smell in the bottle is exactly what one would expect. Visually, it is easy to compare to the bottle of Aunt Jemima pancake syrup in my kitchen. They are almost exactly the same color, I really can't tell the difference. The Rath is definitely harder to see through, and only a little less viscous than the actual pancake syrup.
Apparently VG is thicker than PG, so it took a second for 5 drops to soak into my dry atty. It definitely gurgles more than the PG stuff I'm used to, but I sort of like that. The flavor is good. Not quite as intense as I was expecting, but I really liked it! Very true to its name, but with a slight undertone of pipe tobacco to me for some reason. Throat hit, oddly, didn't seem very strong. That's ok with me, I'm not in to a heavy duty throat hit, of which the 510 is perfectly capable. I did expect more TH from this 24 mg juice, but I actually like it right where it is. Vapor production was phenomenal compared to PG. This I like. It seems that due to its viscosity, a few drops dripped last a little longer than the same amount of a PG based juice.
I usually vape 16-18 mg juices, but wanted an extra kick on this one since I plan for it to be my morning vape. I puffed on it quite a bit yesterday though, and noticed no real difference in how it makes my lungs feel compared to PG. The difference in nicotine density was noticeable. I also tried taking a hit with a paper towel over the mouthpiece, and then did the same with a PG Apple juice. Between the two, there was no difference in the color of what stuck to the paper towel (both actually came through clear). There was no appreciable difference in quantity of residue either. Both residue spots left the same slightly oily feeling when I rubbed them each between my finger and thumb. From these simple tests, it seems that there is little to no difference in the vapors' residues, in spite their vast difference in color and viscosity.
Overall, I have to highly recommend Rath Waffle Juice. It probably won't last long with me, unless I can keep it to JUST in the mornings. I'm now looking forward to trying more Rath juices, and VG certainly has gained my interest.
