We previously had a neff hide and slide oven that started making a loud annoying noise when cooling down, it was an old discontinued model that wasn't worth repairing.
We bought this oven as we are used to the hide and slide door and really like that feature.
The hide and slide door operates a bit different on this oven, the handle doesn't hinge and rotate when lowering the door like our old one but thats not really an issue.
Minor negative points:
The oven cable is quite short. The oven cable was a lot shorter than my old one, this was bit of an issue for me and meant i had to move connection boxes and such.
The oven 'hand holds' used for actually lifting and carrying the oven are quite small and not the most comfortable, but seen as you only really move the oven once it again isn't really an issue.
Positive points:
The oven cooks evenly and consistently to the correctly timings. We previously always had to cook thing a little longer than the food directions.
The slide out rack is useful.
The oven light is bright and can see the food cooking clearly.
We have only had it for a week but so far so good with no real issues.
