I was extremely disappointed with the quality of the panels delivered this time, which I would not have been able to use in the bathroom as I had previously. Whilst there were problems previously I had enough panels to avoid the problems because I over ordered. This time there were a lot of marks on both panels. The lack of close scrutiny in the place that I have used the latest panels means I was able to use them. I would not otherwise. This was after the wrong panels were delivered initially. The colour of the back of the panels has also changed. I would not expect such poor products.
