Very good product but take your time assembling it - the instructions comprise pictures only and you can easily become confused. Suggest you get each panel ready on a table with a strong coffee to hand then take them to the room the desk will placed for assembly as the  finished product is heavy and not easily moved. Drawer runner attachment to carcass is tricky - the screws DO fit through the metal runners despite initial doubts that they are the right size - they need firm constant pressure as you screw them through the holes in the metal - they will eventually click through and the drawers then fit perfectly. Happy with the finished product which arrived on time and undamaged.
