TechPowerUp posted a review on the Logitech G900 Chaos Spectrum Mouse
A quote from the article:
The Logitech G900 Chaos Spectrum Mouse is $140, but Logitech claims that it can be used both wired and wirelessly without any loss of performance. At that price point, it would need to be a lot of mouse with a great sensor.Logitech G900 Chaos Spectrum Mouse @ techPowerUp
