Satisfied purchase!

I am very happy with how fast it had arrived.all part were there and organised properly.the only issue I would say or rather a concern is there are no instructions for piecing it together.I personally know how to piece it together as it is not extremely difficult however not all customers might know how and that's why I've given 4 out of 5 stars otherwise I love it!
