Question: whats the real size of this mice?
Document: Works flawlessly. Nice weight, cool surface feel (like the Lenovo laptops), good portable size without being too small/no productivity issues. Buy it, yo!
About the weight, there is definitely a difference from a wired mini mouse, but I got used to it quickly, I feel now that this is a perfect weight and size mouse! Not too small and not too big, so it's perfect for travel and stationary use.I've owned this mouse for about 2.5 months and the batteries it came with still have 50% charge left according to the "Lenovo Mouse Suite".
When I bought my new ThinkPad, I had a good mouse and saw no need for getting another. But I forgot that my husband needed the mouse for our old computer. So I went for the Lenovo ThinkPad mouse, checking first on the Lenovo site and then Amazon. Amazon's price was just a bit lower, and shipping was free since I have Prime. I'm glad I went for this mouse. It's a good size for my hand and is responsive to movement, clicking, and scrolling.
I went through several bluetooth mice and had problem after problem (Microsoft Sculpt included) After I purchased this one I haven't had a problem since and it feels so good in the hand and it's nice and compact.
I'm hoping it will become "grippier" after my hand has been on it for a while.As for clicking sound, it's just slightly louder than the Microsoft mice, but not really enough to notice or bother.And finally, the wheel action is looser than on either of the Microsoft mice. It's ok, but not as good.
I love the weight of this mouse, its response is good. Just a good all around product. Like most things ThinkPad! It is a little small, those with larger hands may find it a little too small. It is bigger than most wireless travel mice, and not as big as a standard sized mouse.
Nevertheless, I have quite large hands and it has been OK in my hand. Will get used to it very quickly, because it also feels very solid and not flimsy, like some other cheap mice...2) The versatility of that little red track-ball is amazing! You can do just about anything without taking your hand off the mouse, other that for typing.3) Battery life is indeed terrific!
In a few short months, this has become one of two memorable mice I have used over the last 20 years.The first mouse that sticks out as a great mouse that I can remember is the Microsoft Optical mouse. The scroll wheel was an innovation at the time and the absence of a tracking ball eliminated the need for a mousepad on many surfaces and ended the days of cleaning mice.
I have no idea why this isn't standard among mice nowadays.Like the original Microsoft Optical mouse, the hand-feel is just right. There was very little adjustment time and now whenever I'm on a different computer with a mouse, I wish I had my thinkpad mouse.If for any reason this mouse breaks or I lose it, I will replace it with another one and will have no desire to try out a different mouse.
It's small enough to carry around with a laptop, but unlike many other laptop mice, it doesn't cause me to have hand cramps. This mouse has found that sweet spot between portability and comfort.It uses bluetooth. If your laptop or computer has a bluetooth adapter, you do not need to carry around an adapter. Instead of having two pieces to carry around, there is just the mouse. This makes it that much more portable.The rubberized plastic feels great on my hands.
