Worst company and product I’ve ever dealt with. They sent me a defective unit, so I sent it back. They sent a defective replacement, so I sent it back. They sent a third one – again defective. Then they sent replacement filters. Still didn’t work. | They twice sent items to the wrong address, even after I tripled-checked the address with them on the phone. I wasted hours on the phone with them and at the post office. When I’d ask to speak to a manager, I was always told they’re in a meeting. I asked for a manager and repair engineer to call me. No one ever called. One time I insisted they put a manager on the phone, and the rep (ironically named Angel) rudely shouted me down and then hung up on me. | I finally gave up and told them to send a refund – they said that after this whole nightmare, I’d have to pay return shipping. I finally got a rep who said they’d pay return shipping. Defective product, incompetent staff.
