Summary: I preferred the older version for: 1. better finger traction on the wheel I find it harder to engage and increased pressure sometimes results in a middle-click being recorded 2. better hand ergonomics It just doesn't feel as comfortable (a larger bump towards the back would provide better palm support) 3. matte surface more difficult to clean Previous version had a shiny surface that was much easier to clean.
Summary: This is a good mouse. I have it for over one year already, and it still works perfectly. I use it over different surfaces, like bed, sofa, wood floor, my desk, dinning table, etc, and it works fine and accurately. A little complaint: I know it's a mouse for laptop, but I would be happier if the cord was a little bit longer. I normally plug this into the USB at the back of the laptop. With a short cord, the mouse can't really have some big movement.
Summary: I love this mouse. The small size makes it very easy to pack into a bag for travel, and also makes it easier for me to control. I've gone through many mice, and this one is my favorite so far. The cord is short, which is good for laptops, but would make it difficult to use for desktops.
Summary: To be honest, from the price, I thought this was a standard sized mouse. However, my error was not in vain, as my 4 year old Granddaughter uses it (with ease) when she visits me. I'm sure I could get used to it if I had to. Even though I consider it to be a bit on the expensive side, I will admit it's of sturdy construction, comfortable to use, and will probably last longer than many. Therefore I recommend this mouse for those with small hands.
