I am giving the Hamilton beach 6 slice Digital Air fry Toaster Oven a 4 star because this is one small appliance that you need the user guide just to turn it on and until I am completely comfortable using the appliance I will have to refer to it.  When the unit is on and cooking the indicator buttons are red and blue when it is off.  That is something I am going to have to get used to.  I am so used to red meaning off.   The unit when on Air Fry mode is so quiet compared to other fryer's.   On bake mode it cooks evenly and does not heat up the entire kitchen. If you set the timer and turn on the unit to heat up the oven the timer starts counting down, you will have to take this into consideration when setting the timer.
