More than happy with the output and runs continuously at about 50% output, which is still a lot of smoke and readily fills our 20x20 ft stage. Note that if you use the optional radio remote it only give 100% output and so will not run continuously and is a bit noisy. To control the output you need to use the included wired remote or DMX and then it is much less noisy. HOWEVER it seems very temperamental on DMX. The first one did not work at all and the replacement would only work with industry standard stage lighting controllers if I put a DMX splitter/booster next the the machine. Otherwise the machine reset as soon as I increased the signal to about 10%. Worked OK on a Chauvet DJ controller though. Chauvet technical support could not explain this. Still for the price a great output.
