The SteelSeries Rival 650 Wireless is a decent gaming mouse. It's the first wireless mouse in SteelSeries' lineup, and it's nearly identical to the wired SteelSeries Rival 600. It has an incredible sensor with a wide CPI range, minimal CPI error, and low click latency. It has a depth sensor that's supposed to reduce the lift-off distance to 0.5 mm, but we don't test for this. Although it's on the heavy side, it comes with eight 4-gram weights if you want to make it even heavier. It's extremely comfortable for any grip type, but it may be too big for smaller hands. Even though it's wireless, you can only use it with its proprietary USB receiver.
