The most expensive mouse is not always the most suitable for you. When you choose a mouse, you should consider the following aspects.
One, appearance
The first impression is very important, and the pointing device has also no exception. A computer mouse with a good appearance is too fond for you to leave. There are many mouse models, and you are attracted by their colors. Usually there is a layer of gloss oil, conventional oil or rubber oil on this device. Rubber oil will make you feel more comfortable, but it is easy to be scraped; gloss oil can increase the brightness of the surface; conventional oil is generally in silver.
Two, hand feel
The hand feel is relatively significant when choose a mouse, because a mouse with a comfy hand feel will increase your working efficiency effectively. Also you should select your mouse according to your hand size. Except the big sizes, there are a few pointing devices with small sizes especially designed for kids and women.
Three, port
Currently in the market we can find mouse devices with three types of ports: COM port, PS/2 port and USB port. Generally the PS/2 port is able to satisfy the needs of normal users and people in specialized fields. But as the notebook popularizes and the host computer changes, the USB port will became the mainstream little by little.
Four, weight
It is not said that the heavier a mouse is, the better it will be. The performance of a mouse is decided by its chip. A heavier mouse actually can endure a bigger external strength, but its capability would change little.
Five, capability
No matter its shape is good or not, the capability of a mouse is the most important thing you should take into consider when getting one. For the normal users, they are not so demanding on the mouse sensibility, an ordinary optical mouse is enough for them, but for the gamers or people specialized in graphics/images design, they should choose a high-end mouse with an accurately positioning capability.
