You will not believe how much smoke this micro machine can spit out. it takes something like 4 minutes to warm up and load the first shot, but one it is going it takes a few less and this thing can get a huge amount of fog in a medium venue, if you keep pressing the button.
perks: very light, huge amount of smoke, very very small liquid usage, long distance shot
defects: a little slow to warm up, the power cord is way too short, there is no "auto shoot" on the machine, you have to actively press the button, and while you are on stage is not always comfortable, a little noisy.
anyway, for the price, it is way more than expected.
i got 2 and they can really get a medium venue totally foggy.
