plastic junk...not even as good as a regular cart. the so called dripomizer they are selling didn't work at all. I got two. Tasted terrible burnt etc. The drip tips were nice enough--i put them on some regular attys. the "dripomizer" cartos look like a boge with the plastic mouthpiece removed and replaces with drip tip. I put the tip on the boge (bouth elsewhere)...nice clear clan taste. at 2.0 a little hot for my taste i think but solid production for the first hour or so.
