Initial opening of the box, it had a strong electrical smell. Operating the fan was very easy. 2 rocker switches. The fan switch on the left was a little confusing without reading the instructions. Low Fan and High. The heat was delivered very quickly. 2.32 seconds to be exact. Not a heater to be used under the desk to warm the toes. It's more for tabletop use. The emergency off switch underneath the fan is a good addition however wonder if that was really needed since the heater doesn't get that hot.
