Question: What is the battery life?
Document: connects with ease, will order more of these for my other computers, comfortable and great battery life, another good ms product
If you need Bluetooth, this is great. Pairs easily, works well on variety of surfaces and has more than  adequate battery life.
So far battery life has been great. The scrolling is very adjustable in software and I quickly got used to the simulated scroll vibration. Great travel mouse as well.
With RF mouse, you need to insert the transmitted into the USB socket! With the bluetooth mouse, you will free up one USB port and not afraid that you will lose the dongle! Sensitive and responsive. Battery life is acceptable! Glad i bought it!
I am pleased with Microsoft's take on a portable bluetooth mouse. The &#34;virtual&#34; scrolling wheel takes a bit to get used to, especially when you first feel the clicking feedback it gives as you scroll. Battery life seems great so far.
First the battery life on this thing is insane. I honestly don't know how they do it. It works great and scrolls both ways for windows 8. My only complaint is it has this weird tactile feedback built in for scrolling. It doesn't get in the way of operation but it certainly feels strange and takes some getting used to.
Pros-----------1) Size and weight is balanced. Some bluetooth mouse are way too small and light to be comfortable.2) Good battery life.3) Good and high resolution traction on multiple surface including glossy non-glass surfaces.4) Excellent click feel.
I've had this mouse for several months now and still cant get used to it. As a pointing device it tracks well and has incredible battery life, still on original batteries. But the deal breaker is the scroll wheel or lack of. The touch sensitive strip is too touchy. Some times its responsive and others not. it's not smooth and acts very jumpy. it's basically useless as a scroll wheel. do not recommend.
I can tell already this is going to eat a lot of batteries. I own 2 other Bluetooth mice and I recommend that you use Li-ion AA batteries. With medium to heavy use I usually get about 1 year battery life using Li-ion batteries. I can tell you I'm going to be very happy with this mouse.
Comfortable to use, up, down and side-to-side scrolling. good battery life. Bluetooth connected (no dongle neeeded).Accuracy and precision of the mouse is very good for working with graphic software as the resolution is high. The slider bar is not as sensitive as a scroll wheel and is sometimes sluggish and jerky depending on how dry you finger is. With some trial and error, one can get the settings to a satisfactory level.
Answer: I am still on my original pair of batteries. My previous mouse would have been on the third set by now. Simply stated, I like it.
