Well I got my first CE2 R4's today.
The note inside said "max 1mL" of juice per cartomizer...which was a bit odd since these are supposed to be the XL variety. But whatever. Opened one, rinsed it thoroughly, blew it out, and dry-burned it (using my hot pink manual 510). Alas, I didn't do it long enough to see the coil get red. I didn't realize how long it would take to get it to turn red. So it tasted awful, the burnt plastic taste. Wasted a mL of juice.
So I rinsed it out again, removed the end cap & removable inner ring...plunked it into a pot of cold water, and when it reached boiling I boiled it for 15 minutes. Then re-rinsed, shook it out/blew it out...and this time dry-burned with the 510 until the coil glowed red. Took at least 2 minutes of constantly pressing & re-pressing the button (when it cut off) for the coil to get there. Once it got red hot, I did at least three 7-second dry burns. Let the cartomizer cool (it was like crazy hot after that). After that, my juice tasted proper.
But I still
don't like these. Juice apparently leaks quite easily from the cup inside, despite the removable protective silicone ring in the middle. For example, I was downtown and had been using the CE2 for over an hour without problem (but without much satisfaction)...stopped vaping for about 15 minutes & then went to take a draw...and to my unpleasant surprise, I got a fairly large mouthful of juice!!! Never had that kind of baloney with a Boge. Boges 1, ceramics 0.
Plus they don't seem to perform as well, vapour-wise. Definitely not
consistently, at any rate. Throat hit was also noticeably lacking, to the point of being almost non-existent. I was getting the nic...just not the throat hit. I was like "what is this baloney" - so I used the same juice in a standard Boge 510 cartomizer (a new one) and boom - great, consistent vapour...& excellent throat hit. Boges 2, ceramics 0.
The CE2 R4's also...well, felt weird. I'm used to having the filler in there. I don't know what it was per se...but after trying them, I'm not so convinced now that filler is a bad thing. Oh, and the whole "no glue" thing? Not convinced that's true. The non-removable ring with the filler holes certainly looks glued on to me. There's some sort of very visible substance holding it on there quite firmly & it damn well looks like glue, lol.
So I'll still commend
RoyalSmoker for their innovation - the idea has some promise. But I
won't be buying CE2 R4's again. When they develop the CE3's...they should consider making the removable protective middle ring thing out of ceramic. Perhaps a little locking doohickey that can be nudged to slide over top of the filling holes, to ensure no leakage out of them. Those holes should also be a tad larger too: filling is
not easy when the hole is too small to fit a blunt tip syringe (and barely even fits their cheapo, easily breakable plastic needletip). Perhaps a see through gauge on the outside too so you can see when the cup is running low. Or just make the whole thing see through.
One thing's for sure...CE3's are definitely going to happen, because these CE2 R4's are just by no means a happy vaper's favourite. There's just too much inconsistency, bad performance, leakage, and the lack of readiness out-of-the-box for these to be considered anything more than a prototype stage. I'm actually surprised that they produced these in a large quantity, they're so obviously
not ready for rollout. All in all...I still love the standard 510 Boge cartomizers & much,
much prefer them over the ceramics - they hands down beat the current ceramics on every count - so I'll stick with the Boges as my main deal.
Next time I want to experiment (or rather, next time that I can
afford to

), I'll give the LR 510 cartomizers from
ProVape a go (they're 1.5 ohms, which sounds awesome). I look forward to that. Anyone who has tried them with a 510, eGo, or Mega eGo - I'd love to hear your thoughts! You can post here or PM me.
