The Logitech MX Master series has been one of my favourite mice to use. I'm still using my old MX Master 1, which has been with me for 5 years. I work from home which means I use my mouse for more than 10 hours a day, which is a testament of the quality of this product.
The item shipped really fast! I was surprised when the postman delivered it to me. It was well-packed and everything looks great. I'm not sure when I'll start using it though, since my old MX Master just refuses to die.
