There customer service is terrible, they act as if you are the problem when in fact its their product does not work!. They take ages answering e mails/messages. I spent £400 on a pond pump with UV light. The light did not work. After numerous requests they eventually 3 weeks later!, second time they sent one, (the first one did not arrive???) they then sent me a replacement bulb, that arrived and does not work. Asked them to send a replacement light ballast. Now they are asking me to send a video to show it is not working !!!!! I do not recommend this company at all. Terrible customer service and faulty products.
