The mouse is the Minus version which is smaller and lighter than the regular version, and the comparison is shown in the last picture.
The mouse has been with me for three years, and praise be to God, it's still in good condition, but:
There is a problem with the front side button, shown in a separate picture. You have to press hard and push the button in a bit for it to register, and it's annoying to use if you use it, but it doesn't affect you if you don't use it.
Price is by offer. May God bless everyone.
