Missing Mamba Wireless Dock

Hello all, I purchased a Razer Mamba Wireless about a year ago to replace my previous mouse. After plugging it in today, I noticed that the mouse has little stutters every now and then in wireless mode. The receiver is about 1.5 meters away. The stutters are present on both USB 2 and USB 3 ports. The stutters get worse as the battery power decreases. While googling for error causes, I noticed that a wireless dock is included, which you can bring closer to the mouse on the USB cable. Unfortunately, I found out that this wireless dock was not included. I can remember that the packaging was already opened at the dealer. Therefore, the mouse was also cheaper. Unfortunately, I did not notice that the wireless dock was missing. My mistake. Is it somehow possible to get this wireless dock? Thank you and best regards Alan
