One of the benefits that should be mentioned is that there is no double click, which indicates that the sensor is rather good. Extreme precision. BUT! No, not for this amount of money. Before to it, there existed a Bloody R8 that was seven times more affordable. Served without incident for a period of four years, and it is identical in every respect. And she is still employed at this time. I quickly came to regret my decision to switch to a Razer that had better ergonomics. The fact that the battery only lasts 12 hours of active use is the most significant disadvantage, especially when contrasted to the Bloody's 36-hour battery life. Even though the sleep mode is active, it's probably the brightness that puts an end to all of this. The plastic groans, and the most depressing aspect is that it quickly becomes quite dusty and is really difficult to scrub clean. In general, the design receives a score of 5, while the implementation receives a score of 3. If you're going to spend this much, it ought to be made of titanium.
