Anyway it is light. Because it is a left / right object, it is convenient for the right hand to get tired and switch to the left hand and operate. Naturally, there is no button so you can not go forward or back when browsing the browser.
I used the company's old type and it was pretty good so I tried to repurchase it had changed to this product. I like the battery well and the sensitivity is good. Wireless thought that there was stress such as malfunctioning, but it was totally free from the trouble of the cable without any such thing at all
