Summary: I have tried to love the Anywhere MX mouse. It definitely has a nice weight and comfortable feel, and it's handy to be able to click down on the scroll wheel to toggle between smooth and incremental scrolling. It tracks very well on any kind of surface, and the Set Point configuration software is powerful and easy to use. HOWEVER....I have had to buy about 4 of these over the past three years, due to one or more reliability problems.
Summary: I returned Anywhere Mouse MX to the store and perhaps I will buy M705 (it's little obsolete and not the best, but I don't know anything better). The main cause why I don't like Anywhere Mouse MX: middle button doesn't work on scroll. Hyper-Fast scrolling switcher used instead of middle button and it's not configurable because of hardware designed. Sure, I can configure middle button to "Application switcher button", but it's not common behavior never!
Summary: I really liked at first. But the scrolling wheel is terrible. It does not work well with outlook or firefox. I like the fact it tracks on any surface, but all that is lost in the scrolling wheel. It really kills it for me. Escpecially that is cost more. disappointed.
Summary: Started using it and was very happy with it. Despite the fact that I had been using it on a good surface, some time after it started exhibiting erratic cursor movement. Took the mouse back to the retailer and got a replacement. Same thing here! Couldn't use it any longer and had to go back to my M705. Cost me too much money, to recommend it to a friend!
Summary: As some reviewers have already mentioned, the pictures for the product show a matte finish. However, the product as shipped has glossy plastic on the areas where your fingers touch the mouse. If a glossy finish doesn't bother you, then no problem. But for the rest of us, resting our fingers on a glossy finish is disturbing. it makes your fingers feel greasy and is very objectionable.
Summary: I bought the current version of this mouse as a replacement for the original version that I've been using for the last two years and a half. Nowhere does it say that the current version has glossy plastic surface instead of matte black one. All the pictures in all the online stores that I've seen are of the original matte version and I expected that's what I'll get.
Summary: So, the mouse, like every Logitech mouse is good until just about the time the warranty expires. In which case, you get the inevitable and dreaded malfunctioning-click issue. This is the issue where you click or click and hold and it registers either 1 click, no click, 2 clicks, or sporadically registers multiple clicks in rapid succession.
