I have the same model, hexy — I'll share a few things from my personal experience.
- I really like the smoketip ecig. If the cartos weren't a pain in the ..., I would never have switched away from the model. It is a VERY good ecig to 'make the switch' with.
- the 'condom' method is pretty wasteful. I used a lot less ejuice popping the cap on the top, holding the carto at a 45-ish degree angle, and dripping onto the batting inside. You have to go a bit slow; drop on 4 or 5 drops, wait for it to soak in, drop in 4 or 5 more. In this fashion, 20 drops fully restored the carto. With the dripping method, patience is really important. It's like dripping water on a rolled up napkin. It takes time for the water to distribute downward, so it's best to drip-wait-drip-wait-drip-wait-drip-wait. I wait about 30 seconds between drips, turning it each time. After the last set of 4-5 drops, I wait about a minute - just to make sure it's hit bottom, down where the atomizer is.
- the carto lasts longer if you DON'T clean it between refills. This requires that you put compatible flavors on - like, I refilled my coffee cartos with cappuccino ejuice, for example. I also filled my chocolate ones with cappuccino. In other words, the old flavor WILL linger, so I wouldn't (for example) drip bubblegum ejuice onto cartos that came with clove flavor.
- you CAN clean the cartos between uses, but the atomizer inside will take more wear and tear (and so die more quickly), and you will still never fully be rid of the original flavor. Other people have said differently, but this is my experience. I will also say that every atomizer I washed just doesn't quite taste right after cleaning it. I far prefer the flavor-matching method described above.
- learning to refill the cartos takes a little bit of practice. Not a lot, but a little. There's a trick to almost everything with e-cigs. Embrace the idea of learning.
- if you DON'T clean your cartos, you can probably refill them 4-5 times before the atomizer burns out and it's time to throw the carto away. If you DO clean your carto, you can probably refill it 2-3 times — provided you don't destroy it in the cleaning process. I destroyed a few.
- you have an automatic battery, not a manual one. You didn't ask, but you will find reason to wonder at some point. Manual batteries have little buttons on the side.
- the amount of vapor and throat hit are very dependent on the ejuice you're using, and not all ejuice is created equal. I have recently ordered a PG/VG reduction ejuice from juicyvapor.com, in the hopes there will be some 'best of both worlds' aspect to it. I will say that only a few juices I have tried so far produce both as much flavor and as much vapor as the fresh cartos ordered from smoketip. Maybe this is why they offer so few flavors? I don't know. I'm still finding out which suppliers and flavors I like best.
- your carto refilling skillz may have a little to do with the lack of throat hit and vapor - because if you don't have enough in there or it isn't at the bottom, it isn't going to produce much vapor or much throat hit (or taste very good). But mostly, it will be the kind of ejuice you're using. Some are just stronger than others.
Hope that helps.
