Pros: Great look and feel. Good strong Bluetooth connection. Tracks very well. Quiet but very solid sounding clicks.

Cons: As with the other lower ratings here, the left mouse button on mine has been sporadic over the past two months. Any actions that require a click-&-hold (selecting text, dragging and dropping, etc) are virtually useless at this point. I love everything else about, but clicking the left button is a pretty important function in a mouse.

Other Thoughts: Considering that nearly half the reviews here now show a problem with the left button, there's clearly a QC or build issue with this mouse. I'm very disappointed in Lenovo for this. It's tough to find laser Bluetooth mice, and I made the assumption that the ThinkPad name meant something quality-wise.

Pros: great feel. appears to be good quality*.

Cons: *Left mouse button started to 'not always click' a couple months after purchase. replaced batteries several times and blew out with can of air - seems to be a defect.

Other Thoughts: This mouse would a get 5 eggs - perfect, if it wasn't for this defect. I'll be replacing with a different mouse

Pros: its a great mouse. well worth for the price, precise, fits good in my hands, long battery life.

Cons: Turns of at random intervals, but considering the amount of times it was dropped understandable, still a good mouse for being 7+ months old.

Other Thoughts: Not good when i am playing online and it just turns off. Ordered a second one for that same reason.

Pros: -Its a ThinkPad mouse!

Cons: -The left button is already dying and i've only had it a couple weeks at most and have taken very good care of it.
-On Windows 7 it has issues staying connected but this problem is removed when used on windows 8.
-Not sure if this is typical of all of them or just mine, but I had high hopes for this mouse and sadly it hasn't preformed and I can't just go pay for another one right now.

Other Thoughts: Would LOVE another one if it worked properly. I am a very avid ThinkPad fan, and was so excited for this mouse. I am legit sad that it isn't working well.

Pros: All of my impressions about this mouse is based on usage on thinkpad t430 with Gentoo Linux x86_64 Bit OS.
This mouse works perfectlly with blueman, providing execelnt precision and felling.

Cons: In linux is hard to manipulate the wheel speed. Otherwise everything else, speed, precison, fell, mobility is just outstanding every single I own in the past

Pros: Connected without a hitch. Programmable wheel. Small enough for travel. Pretty stylish. Matte finish for grip... frankly I am very very happy.

Cons: None so far...we'll see how long the batteries last.

Other Thoughts: Bought this for use with my MSI GS70 while the figure out the trackpad issues and while traveling... So far, so good.

Pros: Bought for my Surface Pro. Buy while you still can. This is a quality product.

Cons: Was a little costly.
