Bought mine just over 12 months ago. I always found that the auto mode was useless. Either No haze or too much even though there is a 0 to 100 setting, it is not linear in any way. 0 is off, 1 was nearly full output.. Via DMX i learned to live with it, just switching the haze on when needed, but during a busy gig most times i'd forget about it and just leave it off as again, even with dmx control, setting it low produced too much haze and i've set a fire alarm or 2 off with it like that. so I just switched it on for a minute, then off. Not the best way to use one when you've other things to be doing.
It would also have been nice to have some control over the fan, as it is quite noisy in quiet environments.
Now this one is dead, I have to decide if I will buy another, or choose a different model altogether. Someone else said they have had 3-4 of them now and they all fail after a short amount of use, so i think it might be the latter option I go for.
