The CE2's work great for me too.
However, there's a bit of tweaking if you
want CE2's to wick & vape great for ya.
By the way, why are you asking?...lol
Are you getting a yucky taste from some cartomizer polyfill batting?
(that's the interior fluffy stuff that looks like cotton)
If so (if that's all it is), just use a better cartomizer.
The Cartos most raved about in here are the
Boge Low-Res Cartos and
Ikenvape's Low-Res Cartos. Try one of each to see which you prefer...both are nice and both let your flavors come through cleanly. However, there are good folks in here that are better qualified than me to tell you more about them...
(ie: I've been mostly a CE2 guy because I hadn't found anything better, until I tried an IkenVape 901 LR Atty yesterday...wow!!...but that's a different animal and requires dripping unless you're willing to use an additional feeder system with it).
As for non-polyfill cartos, the Sapphire, the Vortex, and the G4's (pictured above) are super easy to re-fill, but their performance is lacking compared to a tweaked CE2. With the G4, and its predecessor the Vortex, you must use the supplied mouthpiece it comes with to make a proper seal, however, they tend to come off rather easily which can cause spills (moreso with the Vortex). Yet, you can still get better performance than any of these even from a moderately tweaked CE2.
I'm also not sold on the "Smokey-miser CE3" due to poor internal design and lack of vapor production. While their tubes are better than clear CE2's, filling them is also more of a chore. Fortunately, CE2's are popularly available in metal tubes as an option, so it doesn't get any more durable than that (the clear CE2's are easier to start with though).
If you tweak a CE2 and take care of it (clean it after 5-10 refills, or sooner depending on the juice you use), a tweaked CE2 can vape really well for you, as good as a low-res atty, and it can last for a few months too. I still have & use the very 1st CE2's that I bought over 2 months ago, and I get about 8-10 refills out of each one between cleanings. The CE2x (aka: fat-wick/revision-4) by RoyalSmokers are the ones I trust (you can get them from -->
GotVapes.com and they're now called FluXomizer Deluxe Cartos). But be prepared to tweak them and clean them periodically if you want the best performance out of them...and they will deliver.
So, among affordable non-polyfill type cartos you're asking about, the CE2 is as good as it gets. And because of their performance when allowed to wick well, CE2's are also used in the higher performing Tanks like the 5ml MapTank or the nicer 5ml or 2.5ml TorpedoTanks.
However, if the taste of the poly-fill batting is the issue here (this is common), then you won't go wrong by switching to an
Ikenvape IKV Low-Res Carto or a
Boge Low-Res Carto which are great for overall ease of use, and produce great flavor and vapor production. These Cartos definitely rank in performance among low-res atties, and can out-perform dual-coil cartos as well, and are easier to use than CE2's.
Hope this helps,
Greeny

Tweaking your CE2's
by Greeny
The key to a great working CE2 is how well you tweak it.
I've tried many different tweaks, yet some of those tweaks
can cause leaks and/or are just too troublesome for many.
The easiest CE2 tweak is simply to replace the CE2's ceramic cup-gasket for the thick top-gasket
IE: The top-gasket is the same thick gasket most people throw away to replace with a drip-tip; it has groves along the bottom that fits perfectly over the CE2's ceramic cup. For one, (1) it creates a perfect seal, yet allows for optimal wicking without any leaks. (2) It keeps the ceramic cup firmly in place which prevents the wicks from getting pressed against the tube's interior walls. And (3), if you use a really thick juice (like I do), this especially works well. In addition, (when using thick juices) you can also sand off about 0.5mm from the groved-end of this thick gasket for superior wicking, and it still won't leak. Use this little thick gasket instead of the one on the ceramic cup, and your CE2 will wick GREAT without letting juice run down the center tube and/or spittling up into your mouth).
On a standard ecig or eGo type batteries, the
2.4-2.6 ohm rated CE2's produce more vapor & flavor with those batteries than the higher-ohm rated CE2's. The higher-ohm rated CE2's are better on higher voltage PV's and Mods.
The clear-tube CE2's are easier to start with (and work with) because you can see the internals & how the gasket is seated on the little ceramic cup when you replace it with the thicker top-gasket. You can also see your juice and know when to refill. This is easier to start with...until the tubes start breaking (which are replaceable). The metal-tubed CE2's are thus more durable, and these come in stainless steel or with a black wrapping around a stainless tube.
