We had a few mishaps trying to get a new oven, wrong measurements, unexpected shapes that didn't fit the gap, then we found this oven on ao.com with easy to see measurements and a handy diagram of the oven shape and dimentions.
It arrived in good time from friendly delivery people and once we fitted it and used it, it's been better than we expected, all in all we are very happy and would recommend not only the make of oven but ao.com for an excellent service.
