Input:
I was surprised at the slowness of the product. My original turn table goes about three times faster than the speed of the Micro-Go-Round. Also, you have to learn to take the items out of the Microwave  immediately or you run down the Micr-Go-Round.
Some of this is just getting used to the product, but, the speed concerns me. Does it make the food go around fast enough to not burn it in some spots?
