Need a cheap wireless mouse for gaming

Hello, this is my first post here :)

Recently, my friend told me he was thinking about getting a new WIRELESS mouse for gaming (he really don't wanna use a wired one), but that he wouldn't spend more than $70. Since he and I are not experts, I thought you guys could give us some advices or models to check out.

I found out the logitech g305 and corsair harpoon wireless could suit, but i prefer to ask.
