I would give a zero. The worst customer service I've ever experienced. Rude, dismissive. Could not care less. I bought a fire suite at a cost of £125. One year and 5 months later, the plug caught fire and melted the surge protector it was plugged into. I rang them to tell them that the fire itself had not tripped the fuse either in the plug or my fuse board and the surge detector had not encountered an electrical surge. They could not have cared less. They still sell the product knowing full well that it started a fire in my home. We were so lucky that we have a fire blanket. Frightening. £125 out of pocket, nothing offered from the company. Just disgusting.
