this all-in-one design seems great on paper, but dropped the ball when it comes to doing both function (microwave / exhaust fan).

first, the 2 exhaust fans while loud and seems to have some suction, it located to far back to work effectively. the fans should be moved closer to the front. also, but button to control the exhaust fans is horrible. it's a touch button, but you have to press it several times to get to your desired option. 

there should be 4 buttons to select which fan speed you want. 

2nd, the door on this is a big wide. you can hid you head on it if you don't play close attention. it's also very awkward since the door is so wide. 

3rd, the microwave function it's intuitive. there is no quick buttons for certain everyday food items,.
