I got a Sicce XStream SDC powerhead off the Amazon Warehouse. I've had good luck ordering off there in the past, usually still new in box. This time my luck ran out and it was clearly used, but was okay with that. Unfortunately I can't get it to work, I was going to send it back but they just refunded me and told me to keep it. When plugged in the lights on the controller flash constantly about every 2-3 seconds, tried holding down/pressing buttons but nothing. Thought about ordering a new controller, I found a part # for it on Sicces website but don't see anyway to order. Any ideas?
