I got what I paid for. The instructions were a little wrong but I worked it out. One of the rails is bent and the vernier on one side was torn.  Product 8/10.
I ordered on Friday for Wednesday delivery as I was away until Monday. The email suggests that delivery may be Monday. However the two packages were left Saturday on my door step, unsigned for with no delivery note or card in the door.  Most disappointed in this.  Luckily for me I have a good neighbour that took them in for me.
