    “Value for money but a few niggles”

    Chose this model as it was a reasonably priced Which? Best Buy and dimensions were suitable. Seems to cook most dishes very well. Very sleek looking. Disappointed that there is no traditional grill pan. The huge roasting tin supplied is not suitable for regular grilling in my opinion. Also don’t wish to use an oven shelf as a grill rack - far to wide to fit in my dishwasher. Glad I kept my previous grill pan and handle. The setting and temperature knobs are really difficult to read as the symbols don’t stand out against the black. Not all settings listed in the manual available, as it covers several models. This led to me mistakenly (but successfully) roasting a gammon joint on ‘plate warmer’! I suggest this makes a bit of a mockery of the settings. Surely on a low setting you should not be able set the temperature beyond a certain cut-off point? All in all a satisfactory purchase not I’ve got used to its quirks.

    “Great oven let down by the dial controls”

    The number of functions on this oven and the internal size make it stand out amongst others in its price range. However, the oven dials are problematic and the oven had to be returned because of it. The control dials press in so they can be flush against the oven facade, however, they get stuck. Also, the function symbols are not backlit and are difficult to read from a standing position.

    “Good but cleaning is a pain”

    Everything works well. But the glass is in two panels and there is nothing to stop food particles getting in between the glass. Hard to clean inbetween the glass panels
