I for 7 months possess the new CSL mouse now it still feels like new:
++ Price / Performance
++ Haptics: feels high-quality
+ Ergonomics: fits comfortably in your hand
+ Accuracy / dpi: for a relatively cheap mouse dpi high-speed, adjustable
++ Design: shape and color (blue light)
+ - Processing: In order to meet the requirements, (with me a plastic part broke something does not restrict the function)
One negative point I can not think, probably also because I could not test reference mice or similar gaming mice.
But it is quite sufficient for my needs, so 5 stars!
