You will like it if

Your counter has 6.4 in (16.3 cm) across and 6.3 in (16 cm) front to wall to give it, with 6.3 in (16 cm) clear above.

The one thing to check first

Depth is on record at 6.3 in (16 cm), and it is the figure most likely to end this search. Measure the space you have against it before anything else. Measure from the very back of the item to the very front, including any drip tray or handle. (manufacturer)
