What is the particular feature you like best?
Powerful smoke machine with excellent value for money prices. This is not a Martin but with a minimum of maintenance (like any machine), it is certainly possible to keep her alive long.
It is no secret: clean the nozzle after each use, drain the liquid and make very attention during transport ...

What is the particular feature you like least?
The sonority like "fun feast" of this machine smoke (very noisy) and the absence of RF remote control
