Excellent product!
Bought the Neff purely on reputation of manufacturer and can't say we're dissapointed!
Installation is easy, fitted perfectly into the old appliance space and looks fantastic.
In our house the oven is constantly on and the rapid warm up feature is brilliant, takes a fraction of the time of the previous oven. We've been cooking throughout the weekend using all the different functions with great results (it even toasts bread better, now that's sad!). Are we happy with the product, extremely.
Can't comment on reliabity yet as we've only had it a week :)
