They rock, honestly.

I absolutely love these little guys. The performance is out of this world. However, things to keep in mind, the juice resevoir is pretty small, I only get about 20 minutes of chain vaping before I go dry. The Mego cleaors last hours, but for some reason, leak more. And that's another thing, they do leak. Be sure to store them vertically or you'll have a mess. In the event you do flood, just blow it out and you're good to go again.
Filling is a bit of a pain, but worth it. I know Volcano has needle tip bottle caps, and they're great for tanko set ups and tube tanks actually, but honestly? Skip them for the clearos and cartos. The needle is too big, I haven't been able to use it without enlarging the fill holes, and this does make the device leak more. Just get a syring body for the pharmacy (or buy one online, they're super cheap) and use the soft plastic needle tip that comes with the clearos. Is it less convenient? Yes. But it also works better.
I highly suggest modding them too. I mean, some of them work alright as is, and some of them, the inner seal is seated such that you'll get a burnt taste and little vapor. To fix a badly seated seal, you have to pull it out and reseat it. The mod I recommend is to pull out the inner seal, and enlarge the wicking notches. You will see an increase in performance 10 fold! It's really not that hard to do either, they're just a bit tricky to get back on, you're gonna want tweasers.
Also, with the rubber cap, you'll probably get a bit of juice in your mouth from a tad bit of leaking and condensation. Easy fix, take the cap off and stick a drip tip in it. The magma drip tips fit like a dream. I use aluminum, but if you're concerned about cracking, you can use the new rubber tips. And they will crack, so try and be careful with them, don't drop them. Though these smaller clearos seem to be sturdier than the megas.
Other helpful hints, to get the most out of your clearo, that is, use up all the juice, be sure to tip the device upside down once you start running low on juice, this will ensure that the wick is saturated up until the very end, and you won't get any dry hits (not fun!!!! throat killers, and bad for your clearo).
One more thing you need to know, don't ever put a cinnamon juice in a clearo (or tube tank for those of you who use them), for some reason, the cinnamon juice eats the plastic. Stick to the metal cartos for those.
