I mourn their loss, they were great! Had 2 of them @ $300 each!
BUT, turn them on, wait a very short time and they would dependably put out the fog for you!
No other cheaper machine has ever been able to do this for me. I am open almost every night of the entire year so these Roscos got plenty of use. I can wait forever and some of those cheap machines make fog "IF" & "When" they feel like it, nothing predictable or dependable about them in the least.
I watch the little light, if finally turns off which means it's ready to work, I push the button and it switches to not-ready and will once again just sit there using electricity, making nothing.
A $10.oo Wall-mart fogger worked pretty good, outdoors (year-round) for maybe 3 years.
I never use great amounts of fog either.
