In the package you'll find the mouse SK-T2, a small CD with drivers and instructions. I chose this model instead of the SK-T1 because it is more suitable for small hands. It is actually perfect for my medium hand but equally comfortable for wider hand of my husband.
Very comfortable to use for extended periods of time. The action is fluid and precise, easy to click but not too ticklish, so you can stay in touch with all buttons without accidental release. My nephew loves this mouse so he will buy his own for his favorite games that require quick response and high accuracy.
I love this mouse, and prefers that I bought for about the same price. I received this model to assess and my honest and unbiased review, but I would have been happy to pay the very reasonable price.
