Positives:
+ Good taste
+ Good steam Development
+ Through the bottom - can coil it can not happen that hot parts in the oral cavity fall (a clear advantage over the Topcoil - evaporators)
+ Cheap Ersatzcoils
Negatives:
- The geometry - deep-seated air pipe - something hard to fill, means that for large bottles without long "nose" the best rearing Liquid with a syringe
- Too much air for my taste; I always keep to one of the air holes, then it goes
- The mouthpiece can not be removed, but what complicates cleaning
All in all, a nice to sighted and good evaporator at a favorable price
