Thats not a bad price. Are those bottom coils or just a rebadged version of the kanger m3? I wonder if they are made of a different plastic...
Honestly if they could make these things with a plastic that wasn;t reactive, i would probably use these exclusively.
the SI CE3 is a bottom feeder. I think they are more resistant to the problem juices than their CE2 long wick top feeder. ask imagine on the SI "ask imagine" thread.
