Summary: Very good mouse. I play Battlefield 3 with it. It works with 2 or if you want it to be more light with just 1 AA battery. 4 ways scroll wheel, 2 side buttons, the scroll wheel have a button that makes it spin unrestrained (need for speed mode :) ). I had bad experience with Logitech sound system but what is good is good and this mouse is excellent.
Summary: The first thing i noticed when using this mouse is the tracking felt inconsistent and inaccurate. Then i realized it has nothing to do with the sensor quality or how well the sensor 'sees' the surface, but it has to do with the designed location of the laser sensor. Most mice it is in the middle, or very near the middle of the mouse. The M705 has it located near the edge of the mouse, nearest your ring/ pinky finger. I believe this is the reason tracking is so difficult.
Summary: I was going to get the very sharp looking Logi mouse that cost more but the guy at Office Depot told me to get this one as I'm not a gamer. I got it home and the scroll wheel feels flimsy when used for side to side. I was going to return it but soon realized that it was perfect for the size of my hand, quite precise, smooth sliding, and I never got tired. Waay more precise than the MS Wireless laser 6000.
Summary: I bought my mouse and keyboard combo and the keyboard as well as the mouse will frequently drop out and not respond as Im using it. Waste of money in my opinion and not enough support on the issue anywhere to even try to troubleshoot and correct.
Summary: Had this mouse for over two years. Almost every button still works, except for the middle button which I broke. Pros: Incredibly comfy for me; Scroll wheel uses a separate button to switch modes unlike the Anywhere MX; Forward and back buttons (I switched these to control the volume); Super long battery life even for a moderate gamer and daily use.
Summary: I am an obsessive person. I prefer lightness in spite of battery life. Nobody needs 3 years of battery life, anyway. That's why I put in a single cheap carbon-zinc AA battery in it. It became so light it could flies! Let see how long the battery would last. Probably I'll put in a AAA battery with AAA-to-AA adaptor to get even more lightness!
Summary: Clicking the button behind the scroll wheel changes it to ratchet or to free wheel. The button is in the way with the scrolling feature rubbing against the scrolling finger. It is important to me not to have the added tactile feel when using the mouse. I would rather have better recessed or just some where else out of the way.
Summary: I'm a graphic designer/web developer/photographer who is admittedly hard on mice. I'm a female with small hands so this mouse fits comfortably. I love the arrangement and functionality of the buttons. I love the weight. Everything about it is wonderful, except that after about a year of usage, the left button gives out, rendering it useless. I'm on my 3rd one in 3 years and guess what? A few days ago, that left button gave out.
