"Terrible experience. I ordered what was advertised as a new WaterTech Blue Diamond pool robot. I received a refurbished Blue Diamond and it runs extremely poorly. The parts that were refurbished do not even fit properly and do not even seem to be replacement parts for this model. I contacted Pool Supply World and was told I need to contact the manufacturer. I was furious. I know what a Blue Diamond should look like and how it should perform because I bought this "new" one to replace my old one. I did contact the manufacturer to tell them what I received and they confirmed that I did not receive a new Blue Diamond robot. After 2 weeks of sending pictures and communicating with Pool Supply World, I had enough. We are going a different route to try to get our money back. We need a pool robot that works. The thing that makes me the most angry is that if I had not had a Blue Diamond in the past, I would never have known that what I received was not a new product. This is disgraceful."
