Only drawback is timer mode on the wired control. It is not working. But I am fully satisfied with amount of fog, powerfull maschine. If there is no wind, it is powerfull enough to fill stage 10x15 meters outside in a 5-10 seconds at full power. If use in a small place inside, for example, 7x8 meters, it is enough to hold a button for only 1 - 2 seconds at full power to fill room with a fog.
