The basic function of the machine is great. It reliably produces fantastic fluff. The benefit of this machine that makes it closer to commercial quality is the adjustable temperature, controlled by a voltage switch. You can read the volts on the gauge. Most people say to start with the temperature maxed out, but this risks burning. Instead, start the machine with the temperature off (all the way to the right). Start the head spinning, then set the volts to around 80 volts. It will take a few minutes to start making food, but you don't burn anything. Unless it is very cold, you shouldn't need to put more than 100 volts.
Unless you get the lid, don't try using indoors.
The packaging is pretty crappy, and ours was dented. Vevor off a significant discount if we kept the machine, which seemed like a decent deal. We're out not for the cosmetic damage, i would have rated higher.
This isn't true commercial quality because it can't make insane qualities of fluff. It can do about 1-2 servings per minute, while commercial is much much faster. I am also concerned about the longevity of that internal electronic controls, because they seem rather anemic. However, for home use or light commercial use (church parties or scout activities) you won't go wrong.
