TechPowerUp published a review on the ROCCAT Kain 100 AIMO
A quote from the article:
ROCCAT expands their Kain line-up with the Kain 100. Sporting the same patented click mechanism and RGB lighting system as its bigger brother, the Kain 120, the Kain 100 features a slightly inferior sensor (PMW3331) and different, but still high-quality materials, all at a relatively low weight of 86 grams.ROCCAT Kain 100 AIMO Review
