This was similar to my first order about 6 weeks ago except I went with a 5 pack of CE4 Clearomizers. As others have stated the CE4's are disposable, but there are a few tricks out there to make them last a bit longer, like pulling the silicon gasket out and running them through warm water or even filling them with vanilla extract to help clean them out. If you just want to try vaping for the first time like me, then they're not too bad. I would recommend a heavier PG mixture on the juice though, like 70% PG / 30% VG and only using the same flavor juice with the same clearo. (I made the mistake of using 100% VG.) The batteries are fine; I ordered the same thing, 1100 mAh twist style - so far, so good.
