Logitech Couch M515 Mouse user reviews (Blue)

Pros Battery life. Customizable software

Cons Heavy, poor ergonomics.
The cursor movement is jerky
The scroll wheel is unstable and moves as you are working
Works poorly on fabric.

Summary I bought this to replace an ageing LG CM - 300. The mouse is heavy, poor ergonomics. The cursor movement is jerky, perhaps due to the fact that the sensor is sealed at the base.
The scroll wheel is unstable and moves as you are working moving the page. And yes, it works poorly on fabric.
I like a good mouse and am prepared to pay a premium. This mouse It costs 3 times more than my LG. Apart from the cost, this is very poor product.
I have gone back to the LG. I will buy another after it dies. M515 mouse is just terrible.

Pros Sealed sensor
multi-surface pointer control

Cons ergonomics
feels cheap

Summary I purchased this to replace an older MX mouse. After a few hours of using the mouse, my hand hurt like there was no tomorrow. I thought the sharp pains it caused in the top of my hand would never leave. The ergonomics on this mouse are terrible. I would not recommend this.
