Really 4.5 Star, see below.
Delivered well within the stated time frame.
Very well packed, the box was even strengthen round the edges with hardboard, a lot of polystyrene but that is still the best way to protect a product like this.
Assembly was easy apart from the keyboard tray runners but that was my fault thinking they were left and right handed which they aren't, these are also ball bearing runners which I was impressed with.  Beware that the runners are very greasy so a good wipe with a cloth and lots of hand washing required.
Once assembled the desk looks very smart and is indeed functional, my only comment is that there is some horizontal wobble, the desk could really do with cross bracing at the back instead of the horizontal brace.
