Features: 2.4G wireless plus Bluetooth function; Product workmanship: it's normal. It's more comfortable because it can be charged, so there is no need to replace the battery. The back is more comfortable with less seams; The grip can only be said to be too big, but the hand is fine, especially the position of the side keys. I bought Lenovo's Xiaoxin Bluetooth mouse before, but the side key position is too awkward to return it. See the figure for details. The first is PM6, the second is Xiaoxin, and the third is the previous mouse.

Features: The manual says that Win7 is not supported. The previous old computer is still a Win7 system. Try it at night when you have time;

There are two things I'm satisfied with. First, the width is appropriate. 2、 The little finger position of the right ring finger is designed to be extremely comfortable. Disadvantages: the left thumb position design is unreasonable. It is suggested to learn from the minibus snake. The mouse is very light overall. The battery didn't work when I first got it. It collapsed after being fully charged for less than a month. Then I found that the more I used it, the more I used it. The battery has returned to normal. Didn't pay attention to the specific working hours, but it doesn't look like it was fully charged or not charged when I first got it

The mouse is really practical, easy to use, long standby time, strong~you buy this mouse
