Disclaimer: I recently had to switch to all VG liquids as I have developed a sensitivity to PG. All my liquids now are roll your own.
As in the past I still cut my VG with distilled water and these all VG mixes are very similar to what I used before wrt liquid viscosity. For comparative purposes only VG is known to:
- had a certain amount of sweetness to the vape. This is a moot point here;
- produces more vapour than straight PG liquids;
- produces a milder throat hit than what is produced with a PG blend; and
- diminish flavour delivery. Although the latter may be true, rolling your own alleviates this conception.
First Impressions
- the cartos metered in at 2.6Ohm, they are designed for 3.7 – 4V vaping;
- they are stainless and come fitted with a drip tip;
- they are only slightly longer than a normal carto (2mm);
- they take 30 drops on a fresh charge;
- the polyfill batting seems normal complete with protective sheating. However, as others have observed, it does seem to be “looser” compared to other cartos I have tried; and
- the centre post seems to be adjustable. I have played with mine in both directions and nothing happened?
As a vaper I am critical wrt equipment. I believe when we receive our package from the postman, whatever we receive should be ready to go without having to fuss with it, whether it be a device, atomisers or cartos. No fussing with these cartos, they simply rock!
Discussion
These cartos where tested on both the eGo at 3.2V and my box eGo at 3.7V with an AW 18650 - 2600mAh power source. The liquid used was RY4 and Blackberry Menthol @18mg. The liquids where all VG at a 80/20 ratio VG/H2O
Others have described the draw as loose and I support these findings as well. However, as I do not like an airy draw as discussed in previous reviews, the draw on this cartomiser is anything but airy. Loose yes, but not airy, if that makes sense.
I installed the RY4 freshly charged carto on my eGo and gave it a priming puff. I then took a normal 2-3 sec hit. Wow! I am impressed. Full flavour was delivered with a decent throat hit and plumes of vapour, although the latter is to be expected with my mix, I believe from my experience, they are great vapour generators regardless.

I then installed the BB Menthol one on the eGo. Same observations as before, with the exception of a greater throat hit, expected with a menthol vape.

The cartomiser delivered straight out of the box, as one would expect a carto to work. One did not have to go through any funky taste etc... the liquid flavour was fresh and precise. The draw was extremely smooth, full and easy. I believe it has everything to do with the looseness of the filling allowing unrestricted wicking to the atty. This coming from an all VG liquid is something indeed.
Next in line was my 3.7V eGo. Same results as previously discussed, but a much warmer vape. Increase all ratings by 0.5.
I have not tested them above 3.7V at this time. I particularly do not want too LOL. I want to enjoy these here for another day

, before I stepped them up to 4.2 and 5V, because as we know once we go up we can't come down.
In conclusion I will follow up as the testing continues. IMHO these cartos absolutely rock. These cartos are easily kept moist. I believe this is by design, so kudos to the developers. I add 10 drops every so often just to maintain them moist. Sometimes I will get a gurgling sound, which tells me they didn't really require a refill.
I didn't understand the need for such a contraption, dripping a carto. Many have adopted this habit with the E2s (shakes head), what is the purpose of the E2 if you are going to drip with it. These on the other hand are just a convenient way to refill as required. Furthermore, what really like about these, although using all VG liquid, not once did I have to blow in the end for the liquid to find the batting.
Yes folks we have a winner here. Well done, and Isaac, you better bring in a ton of 'em because they will not last.
