Inside the environmentally friendly packaging one finds the dongle cushioned in foam along with a quick start guide.
Looks
Visually, the HyperPolling Wireless Dongle is nearly indistinguishable from the wireless extender the Viper V2 Pro (among others) regularly ships with. However, whereas the wireless extender has a USB Type-C and Type-A port, the latter of which the regular dongle is inserted into, the HyperPolling Wireless Dongle only has a single USB Type-C port, and inside one finds a full-speed (Nordic nRF52833) and a high-speed MCU (NXP LPC5528), which are required to establish 4000 Hz wireless polling.
How it Works
The physical setup is very straightforward. Using the USB Type-C to Type-A cable included with the Viper V2 Pro or any other compatible Razer wireless mouse, the dongle is first connected to the PC.
In order to work, the dongle initially needs to be paired with the mouse. This step requires Razer Synapse.
Once the pairing has been completed, Synapse is no longer strictly needed and may be uninstalled. Under the entry for the dongle, if needed, one can unpair the dongle and newly pair it with any other compatible Razer mouse. Furthermore, one can choose whether the LED on the dongle shall display the connection status, mouse battery status (green, yellow, orange, red), or a battery warning only.
Polling rate adjustment is done under the entry for the mouse, where the two new polling rate options show up. All the polling rates previously available on the regular dongle for the mouse (125, 500, or 1000 Hz) are available as well.
When using 2000 or 4000 Hz, there is a trade-off involved. Battery life is a function of the set polling rate, which is why a polling rate of 2000 or 4000 Hz will significantly cut down expected battery life. According to Razer, the Viper V2 Pro will last up to 80 hours at 1000 Hz and around 24 hours at 4000 Hz, which is a reduction by 70%. In my testing, the battery life indicator within Synapse went down by 10% for every three hours of usage at 4000 Hz. Assuming linear consumption, expected battery life at 4000 Hz would therefore be around 30 hours on the Viper V2 Pro.
On the Viper V2 Pro, Synapse includes a setting called "Low Power Mode" when using a polling rate of 1000 Hz or less, which allows one to define the battery status percentage at which Low Power Mode is entered. In Low Power Mode, the maximum tracking speed and acceleration of the sensor are lowered, which is achieved by lowering sensor framerate. Since polling rates higher than 2000 Hz require a sufficiently high framerate, this option is no longer available and therefore grayed out when using a polling rate of 2000 Hz or higher.
