Item arrived safely but with some incorrect fittings (I had to buy some screws).
It was fairly straightforward to built and parts fitted accurately (though it is worth taking a moment to check you have each component the right way round - notably the rear panels).
It is also worth using the internal mounting bar to mark your wall ready for drilling before you construct the cabinet (lesson learned there)!
Finished result is stylish with a reasonably 'solid' feel.
