*by S***N on 12 April 2021*

I was nervous about ordering this product but after doing so I am very happy with the product. After placing the order I was contacted to confirm that the sizing was correct and that I was happy with the actual item in the order, in case it wasn't what I expected, I thought this was excellent, saving them and me any hassle returning goods over such a distance if not what I thought it was meant to be, it then arrived well packaged ahead of schedule. Works as expected.
