I just want you to know how dissatisfied I am with this product. I just wanted simple mouse, bought this one and then discovered that the scroll wheel moves in the opposite direction of every other scroll wheel I've ever encountered. To fix it, I had to download a bloated app that makes unnecessary requests to remote servers and now I've discovered includes some kind of pseudo-AI ******** feature that's creating unnecessary directories in my home dir. This is ******* outrageous. This product is not the first item I've bought from logitech, but it will be the last. Sorry for the foul language, but sometimes it's appropriate. I hope you can sense how all of this makes me feel, and I hope you understand I'm not alone. Most users won't care, but for those who do, they'll be exactly as angry as I am. You're alienating a minority to offer a new feature to the majority that they don't care about. It makes no sense. I recommend that you change course NOW.
