Over / Under on average buttons used on a microwave....

3.5

There are like 25 buttons on an average microwave.  I use 2. Under.

GO!

4

but those are  '1 Min'   '10 Sec'   'Power' (or start) and    the 'cancel /stop' button

The button that you press to open the microwave doesn't really count does it 

Never used those automatic presets for reheating or defrosting 

I remember the old two dial set up no buttons just the heat setting and the timer dial. I think you can still get those 

I remember back in the late 80's having a microwave was considered a luxury item 

I use the potato button and popcorn button as well as frozen dinner besides the 1 min or plus 1....

Do they count....

In memory of Detox…

Only poor people use microwaves 

hmm same 2 buttons only 

30 seconds 

Popcorn 

I use pretty much all the numbers, but as efficiently as possible. Everything gets :33, :44, :55, 1:11, 2:22, 3:33. So actually 5 numbers and the start button. I don't think i microwave anything over 5 mins.
