TechPowerUp posted a review on the ROCCAT Kain 200 AIMO
A quote from the article:
The Kain 200 is ROCCAT's wireless addition to the Kain line-up. Much like the Kain 100 and 120, the Kain 200 has a highly sophisticated button mechanism, premium materials, and a fairly unique right-handed ergonomic shape. The biggest difference is the sensor: PixArt's flagship model for wireless applications, the PAW3335.ROCCAT Kain 200 AIMO Review
