yup not a fan as the original e2's give a nasty chemical taste
I have the original 2 hole and the 7 hole revision ones and can soooo appreciate what you are saying.
I do have mine working right now but it involved washing/soaking in hot water, dry burn and rewash/dry burn, replacing the inner cap with a silicon o-ring and "fluffing" the wick with a needle.
I have some replacements that will be shipped with the modifications and ceramic cup though so we will see, and have been assured by the manufacturer that only the ceramic cup version will be shipped from here on out . I am waiting on the reviews once some people receive them before placing that order.
On that note, do I like them better than 510 cartomizers with the filler? Yes
Do I use them over my Joye 510 atomizers and cartridges? yes
Do I like them better that dripping? Yes
Are they long lasting? yes, 3ml per day alternating 2 cartomizers over 8 days on my eGo, 3 cleaning/dryburn cycles(4 if you include the initial cleaning) and still working like new. The manufacture recommended 4 refills then using a new one.
Overall I find there is less fiddling to get them to work right than atomizers/cartridges and best of all no primer puff required.
I have tried to get the wife to convert to vaping for over a year with little success but she is liking the CE2 cartomizers over the atomizer/cartridge and the Boge cartomizers we tried.
Wifes review was that these cartomizers were the closest to actually smoking that she has tried yet. I take this as a positive since she has been resistant to giving up smoking but is using these and cutting back on her cigarettes.
This is just my

, I am in no way affiliated with the manufacturer, am not a reseller of their product and do not receive compensation of any kind.
I encountered problems like others with this new product and used the recommendations of others to troubleshoot the ones I have to work and am very hopeful that the newest version being shipped gives the working out of the box solution we(the consumer) want.
All the best, Happy Vaping,
Wing.
