The Good
The Bad
PV4 is a breath of fresh air for e-smokers who find RY4-based e-liquids overly sweet.

I’ve been writing e-liquid reviews on eDripping.com for nearly two years now, and in all that time there’s one aspect of the e-cigarette hobby that I’ve never quite understood: why so many people love RY4. When Ruyan invented the electronic cigarette, they set about creating various e-liquid blends and numbering them RY1, RY2 and so on. RY4 seems to be the only blend that has stood the test of time. Practically every e-liquid vendor in the United States has their own version of RY4, and if you run a quick search for “RY4″ using the field near the top of this page you’ll see that I just about always give them neutral or negative reviews. Why? Because I just don’t get RY4. It’s a blend of vanilla and caramel, and somehow you’re supposed to interpret that combination as “tobacco.” I sure don’t taste tobacco. I taste candy — and often, bad candy at that. Well, folks, Prime Vaping PV4 is about to change all that, because it’s an RY4 e-liquid that actually has tobacco.
Prime Vaping’s major selling point is its own tobacco extract, which the company produces in-house. On its own, tobacco absolute doesn’t really taste like tobacco — it’s slightly bitter with a distinct “ashtray” aftertaste. Mixed with the right combination of other flavors, though, tobacco absolute does lend a distinctly cigarette-like flavor to an e-liquid. PV4, more than any Prime Vaping e-liquid I’ve tried to date, gets that proportion right. The “ashtray” taste might become a bit disconcerting as your atomizer or cartomizer starts to run dry, but for the most part PV4 produces a very nice tobacco flavor.
As I mentioned above, the typical RY4 e-liquid contains a mix of vanilla and caramel flavors. Prime Vaping PV4 has both of these flavor notes, and along with the tobacco absolute it contains a second flavor I’ve not detected in an RY4 e-liquid before: coffee. The coffee note adds a slight touch of bitterness that the very sweet RY4 has always needed.
The only real knock against Prime Vaping PV4 is the vapor production, which is a bit less than I’d expect from an e-liquid with 30 percent vegetable glycerin. Either way, though, PV4 is by far the best RY4-inspired e-liquid I’ve ever reviewed. If you’ve tried an RY4 e-liquid in the past and wished that it had some tobacco flavor to balance out the sweetness, Prime Vaping PV4 is an e-liquid you should try.

















OK – PURCHASED A 3-SAMPLE PACK FROM PV INCLUDING LOVE FROM ABOVE (NAAH), TANGO (YES!), AND PV4. THE PV4 IS VERY UNUSUAL, FRESH OUT OF THE BOTTLE – *VERY* EARTHY, ALMOST REMINDING ME OF LOAMY SCOTCH AND MUSHROOMS!! WHILE NOT UNPLEASANT, I AM INTERESTED IN SEEING IF THE TASTE CHANGES TO SOMETHING A LITTLE LESS EARTHY WITH STEEPING….MUST BE HONEST AND SAY THAT HIGHBROW VAPOR’S RY4 IS STILL MY FAVORITE – NOT THAT THERE CAN’T BE TWO INTERESTING RY BLENDS FOR ME, B/C I SURE HAVE SPENT $ ON MANY TERRIBLE RY JUICES! THANKS AGAIN FOR ALL OF YOUR DETAILED REVIEWS – FEEL LIKE I HAVE AN EDUCATED CHANCE IN BEING SATISFIED WHEN I MAKE A PURCHASE.
