Bluetooth mouse utility-revolution is not yet successful, but efforts are still required for Bluetooth

The Bluetooth mouse we purchased last week has been back. fortunately, it was the first time I used a wireless mouse. It was good to feel that there was no tail restriction and it was very convenient. There are two aspects to my worries. On the one hand, there are still limitations in buying such a thing online, I have never touched it myself, but I am very enthusiastic about the seller. I also took a picture on the spot to show it to me, but the mouse still seems a little big, and the buttons are very hard; the second worry is that the bluetooth technology itself does not seem to be perfect. Let alone the interference problem between 802.11 and (I have no chance to test it ), there will be a delay in moving the mouse itself. there will be no delay in the process of continuous movement, but there will be a delay at the beginning of the movement after a pause, and I am a little annoyed with the acute.
I don't know whether the mouse is temporarily sleep for power-saving purposes, and then restarted, or the defects in the Bluetooth protocol. I searched the internet for Bluetooth mouse over 1000 of Logitech, which also caused the above delay, so it should not be a problem with mouse design. it seems that the revolution has not yet succeeded, and Bluetooth still has to work hard!
But to be honest, it's really nice to be wireless ~! Haha
