Hi Paul
I can only speak for the Look solutions Unique Model 2 hazer that I own. This hazer has a proper shut down procedure that purges the heater element to ensure no nasty goo stays in there. So, if you put it through it's shut down sequence you're unlikely to have problems. if however you just switch it off at the end of the night you're asking for trouble. It only takes a couple of minutes to shut down properly, so not much of an inconvenience.
On the subject of smoke machines, I bought a new small ADJ smoke machine a few weeks ago. Used it once for a couple of hours, stored it away for a week and it hasn't worked since
, problem is I can't find the receipt so can't really send it back. Having said that it wasn't expensive but it's still damn annoying. I suspect it's the pump that's shot.
Cheers
Jem
