I did not like it, so I returned it. The electronic controls are cumbersome, non-intuitive, and completely unnecessary. Simple buttons would do the job. I don't need a computer to turn on a light and a fan. Cosmo has overthought this appliance to appeal to the touch screen generation at the expense of practicality. The LEDs are blue, dim, and non-serviceable. They look like night lights, not cooking lights.  The thing has 2 functions, light and fan. With all that metal fab into a solid case is it that hard to use a decent light with all the variety that is available??? The case is attractive but super sharp on the corners. Watch your head and keep a stitching kit handy! One thing is good, fan is powerful.
