Summary: I love the idea of a Bluetooth mouse so you don't need a separate usb dongle. However, I could not get this to pair with my computer. I consider myself a technical person, but after several reboots and enabling / disabling bluetooth, I have up and returned the mouse. Great build quality, very sleek, and I love the idea of the multi touch surface. However, I couldn't get it to work! Expensive too!
Summary: Logitech sent me this mouse to replace a defective M series mouse that had been discontinued. I have been using for about four months. During the first month, it continuously lost connectivity. I discovered that i had a bad bluetooth dongle which was replaced. The mouse seemed to work ok after, but has always been somewhat erratic.
Summary: The perfect travel mouse. Unlike most, this is very thin...making it unobtrusive in a briefcase or everyday carry. I am using this with an 8 in tablet, and it works perfectly. If you are using windows 8, then the surface works as a scroll wheel. In all, a superior design.
Summary: I really like this mouse. It has been working great with my Windows 7 Laptop and the K810 keyboard. The mouse is pretty small and light which is a good feature for travel but makes some of the gestures difficult to pull off. For example, swapping from application to application by doing a 2 finger swipe is difficult because you have to hold the mouse in place with two fingers and then try to use two more to do the swipe.
Summary: This mouse works great on my Yoga 2. Easier to handle Win8 with a good mouse. Very precise and consistent handling. Small and thin enough to pack with my laptop. Didn't require much practice to learn features.
Summary: I've had T630 for about a month. I almost didn't buy it because of its small size. I thought it would be too small for my rather large hands and stiff fingers. Instead I find it very easy to grip on either side and lightly touch the upper right and left corners without confusing the poor thing. It's not perfect -- the scrolling function doesn't work as well as I like on my Lenovo Yoga and Lenovo Miix 2 -- but it's the best I've found to date.
Summary: I loved the mouse it looks gorgeous and it's very reponsive, but it kept dropping the bluetooth connection. Turns out that one has to disable device power management in the Bluetooth adapter in one's computer- then all's well
