Vortez tried the SteelSeries Rival 310
A quote from the article:
The Rival 310 is running a powerful 32-bit ARM CPU, allowing all sensor processing to be carried out on the device itself, helping to decrease any latency and also allow profiles to be saved onto the device for eSports. Similar to the Sensei 310, the Rival also offers split trigger buttons bearing OMRON switches underneath.SteelSeries Rival 310 Review @ Vortez
