I bought this to replace an integrated Miele freezer which had failed at 12 years old. The size is essentially the same, but I'm finding the varying style of compartment more useful than the all-drawers design of the Miele.
Building it in was fairly straightforward, although the instructions are in the form of a large sheet of diagrams without any accompanying text (presumably in order to be language-agnostic). It was necessary to spend an hour or so to correctly identify the various parts and to work out exactly what went where. The positioning in the enclosure has to be accurate to the millimetre, so do take the time to get it right, as otherwise bad things can happen, like the door won't close.
All in all I'm happy with it, and did I mention that the price of the equivalent Miele unit is £700 more?
