I just got a used Razer ouroboros and it does not have the usb cable or the dock. I assumed these things would be easy to order off of ebay but I can't seem to find them. I also need a AA rechargeable battery.
Razer sells them. if it's not on the website you will have to call them. Walmart has the batteries though. It is a fairly new and expensive mouse parts are hard to find great mouse though I love mine.
