I love this little mouse. I wish it had bigger side buttons and didn't curve inward on the side (that took some getting used to) and you REALLY need to make sure a smaller mouse will be comfortable for you. I felt awkward and clunky for a the first few days and then BAM my hands got used to it. Same with with the G600. It's massive and heavy and this is tiny and light lol I adore them both.
For it's price it doesn't have as many features as other mice in it's price but it's gorgeous and well-made.
I adore that the mouse turns off if you go afk. The battery life has been long and strong. I can place the cord anywhere and it has not lost connection once (I've had it for a few months at the time of writing this) I love using it with my Logitech G600 will remain connected. It has no issues staying connected. I've also heard that you can use it on multiple systems at once. It's lightweight and has worked on multiple surfaces.
A lovely comfy small mouse that I've grown to love.
