I tried many expensive mice and they broke in months so decided going for cheaper ones as its not worth at all buying top ones which im just able to use for couple months.I play CS:GO with 54.5cm/360 to 19.3cm / 360 without any acceleration and I use Windows 10 Pro 64bit.

WMO (this one exactly:on ebay from takasta, black matte $23.99)
-Not sure if i will have neg accel, whats the lowest sens that I wont get it?
-Only 400 DPI, bad for high sensitivity because of having high ingame sensitivity which skips pixels.
+More durable as I heard.
+Better shape imo (also similar to many mice like Zowie AM, Kana v2, Xai, Kinzu)

G100s
+Has adjustable DPI.
+No acceleration.
-Not so durable.
