1, Bluetooth mouse has a built-in Bluetooth chip, which is protected by patent technology and is much more expensive than the general 2.4g wireless mouse chip. Therefore, the cost of the whole mouse rises, which makes the mouse much more expensive.
2. The general wireless mouse uses 2.4g wireless technology, and the patent fee is very low or even no patent fee. Therefore, in order to avoid rising costs, cheap wireless mice all adopt this technology.
3. The performance, power consumption and radiation of Bluetooth mouse are much better than ordinary wireless mouse, which is one of the reasons why it is expensive.
