Review: Unexpectedly Good - Coming from Logitech MX Master 3S and a first time Track Ball mouse user, this product is amazing. It takes some time to get used to but this feels great in the hand. The built quality is a tad bit less compared to MX Master but at least it doesn't have the rubber coating that MX master have that disintegrates over time. Very good value for money plus the desertcart discount!

The scroll wheel has not been working properly (Laggy) fresh out of the box and it kept getting worse. Disappointed as this is not a cheap price for a mouse.
