Summary: The basic features of the mouse work with the Mac, but not the side to side scrolling, which is exactly what I bought it for. Logitech should not advertise that this mouse works with a Mac. It doesn't. Even Logitech support forums admit that it doesn't fully function with a Mac. Booooo.
Summary: How could logitech put out such a poor product? These mice may have pretty paint jobs, but they don't work properly. The pointer is not precise at all, and you have to make constant adjustments to put the pointer where you want it.
Summary: I normally enjoy Logitech products. I did not immediately use the mouse. After the return window expired, I tried to us it. Dead mouse walking. I still will buy Logitech, this experience has tainted my appreciation of log products a bit.
Summary: I was a loyal Logitech consumer but now I'm disappointed. The sensitivity is worse than the M305 which is what I had before this one (on which a button broke with normal use which is why I bought this one). Also, the wheel tilt feels awkward compared to the M305.
Summary: SO I GOT THIS MOUSE RIGHT, I WAS SUPER EXCITED BECAUSE I HAD A DIFFERENT WIRELESS MOUSE BEFORE AND IT WORKED AMAZINGLY AND THEN IT GOT OLD SO I GOT THIS MOUSE. I PLUGGED EVERYTHING IN AND IT DIDNT WORK!!!!!!!!!!!! IT STARTED TO WORK AND THEN DIDNT!! I OVER THIS PRODUCT!
