Oggfader Wireless Mouse for Laptop 2.4GHz Wireless Gaming Mouse USB Receiver Pro Gamer For PC Laptop Desktop Blue

Good value, as a back-up.

I bought 3. I used one of these for one day and it was fine. On day two, the clicker started to 'DOUBLE CLICK' - every time. It then became impossible to 'single' click. This is disgusting, as it can actually become dangerous when the second click (of a double-click) - clicks on something that the first click enables. When that happens, the second click can enable something that you did not authorize and /or want to click on. That is more than just a major pain. So I suggest buying another brand. I already threw it in the trash, as it is not worth more of my time to ship it back. Sometimes cheap stuff is cheap for a reason.
