The Corsair M65 Pro is an extremely popular gaming mouse, with a 12,000 DPI sensor and custom RGB lighting. The mouse has once again dropped to $29.99 on Amazon—the same price it was during last year's Black Friday.

The M65 Pro has a lot to offer for just $30. It has a 12,000 DPI sensor, adjustable weights, and a total of eight buttons. You can customize button mappings and RGB lighting with Corsair's CUE software. The mouse also uses Omron switches, rated for 20 million clicks, so it should last you a while.
