Very nice and easy to use fog machine. Honestly I didn't read the instructions and just plugged everything in, pressed the manual fog-release button and it worked perfectly. Very self explaining design and great product.
Fog amount was also pretty good. For outdoor usage, just use the interval feature to provide enough fog even when the wind is blowing a bit. For inside usage, don't use the interval feature too hard, otherwise you won't see your own hand in front of your face any more :-D Just one klick of the manual fog-release button and an area of ~ 30 square meter is completely covered in fog.
Warm up for this machine takes around ~5 minutes.
Hope that helps - RT333
