Question: Does this mouse have a "scroll wheel click and drag" function? This is essential for working with 3D programs such as SolidWorks and AutoCAD.
Document: I find I don't need a mousepad/gel pad/angling my wrist weird anymore. The R and L buttons work perfectly without confusion with just the slightest purposeful tap. Overall, another very well designed peripheral from Microsoft (as I expect).The ONE thing about this mouse is the scroll function. On a long webpage/Excel page, it is very easy to scroll down quickly with a scroll wheel. There is no wheel on this mouse, just that silver touch line you see in the picture.
I find myself only needing a mouse for certain features and touch screen for quick taps to open programs or select items.The pairing with Windows 8 was very simple; just select the device with your Bluetooth on. The power button on the bottom is easy to find and activate to save battery life.The mouse button use is intuitive and the click feedback makes it operate much like other mice. The slide to scroll feature works but does take a little getting used to.
Not recommended. I questioned the size of this mouse when I bought it, but size has actually been little problem. It doesn't cramp my hands or anything like that.There are several usability issues though. Most glaring is the lack of a middle click function, which I use a lot. Another annoyance includes inconsistent scroll speed. I seem to scroll at different speeds depending on which application I'm in, and from one time to the next.
This mouse is very sleek and compact. I like that it is bluetooth so you do not need to take up a USB hub. It works on a lot more surfaces than my old wireless mouse. It is touch sensitive so you can scroll up and down much like a touch pad on a laptop. Cons: a little small if you have large hands, and no mouse wheel click (that I have found so far).
This mouse does not fit my hand very well and every click of the button seems to put my fingers in an awkward position further adding to the discomfort. In addition to this, the absence of a scroll wheel, makes scrolling web pages and documents feel very unnatural. If you are used to using a scroll wheel, then you will more than likely find the absence of one quite frustrating.
Overall I&#8217;m pleased with the wedge touch mouse. It&#8217;s Bluetooth, super small and it works as a mouse + kind-of touchpad. The mouse wheel has been replaced with a touchpad-like area.I can&#8217;t say there&#8217;s anything wrong with the design or the mouse doesn&#8217;t function.
The Microsoft Wedge Touch Mouse is an aesthetically pleasing mouse optimized for Windows 8, and is advertised as working with most tablets and laptops. I was quickly able to pair the mouse with my Windows 7 laptop and download the software from the Microsoft Device Center, which allowed me to customize the settings and do things like assign mouse buttons to do different things in different programs. The whole setup process was quick and intuitive.I tried to mouse on several surfaces, including a wood table and a granite kitchen counter.
You can even identify what, if any, programs have trouble scrolling using the touch gestures, adjust scroll speed, enable/disable flick gestures, etc.The single finger scrolling works well, as do the flick gestures. I hold the mouse between my thumb and ring finger to avoid having any issues with gestures, etc. I find the mouse to be very responsive, and have had no issues using  it over the last week.
First, it appears that left and right on this mouse, has the same function as up and down. The functionality is poor as there is not even a middle mouse button equivalent on it. The right click is difficult as if your finger gets close to the edge, it does not right click. With a tiny mouse, that happens often. I cannot imagine where this would be useful.
I got this and a Microsoft sculpt mobile keyboard as accessories to my Surface Pro. In theory this device should be great - compact for travel, good movement and quality feel. In application, it has to be one of the poorest quality tracking devices I have ever used. Despite trying this on multiple surfaces, it tends toward cursor-jumping on the screen and click-locking (like locking into drag-drop mode with no figure on the mouse).
Answer: There is no scroll wheel. The top of the mouse acts like a track pad so you click and hold and move another finger to operate it. It is kind of a track pad/mouse hybrid. I love it but it may not work quite so well for you if the scroll wheel is essential.
