However, it starts to become rather in the lower middle range of mice, I would advise the G500S because firstly, the G500S mouse is more comfortable (I tried and I have heard both good) and more manageable, it has nothing to do with the G400.
And secondly, the wire was cut at the mouse-wire connection (not wireless-USB socket, this is why I said) to which rendered virtually unusable mouse (It should patch up with Scotch or fixed paste, impractical ..)
The cord is surrounded by the G500S, coupled with a kind of string which makes it more resistant it.
However, I suggest you be careful not to pull on the wire to disconnect and to take precautions when it is moved.
