TechPowerUp takes a look at the ASUS TUF Gaming M5
A quote from the article:
There is a huge list of big gaming mice out there, and a much smaller one for small ones—the ASUS TUF Gaming M5 tries to improve this ratio. It might be small in size, but it's not cheaply made by a long shot. It features a great optical sensor, main switches rated for 50 million clicks, and Aura Sync RGB lighting.ASUS TUF Gaming M5 Review
ASUS is definitely one of the most respected hardware manufacturers around the world, and they are not new to the peripherals market either. They have a few different lines of gaming-related products, and the TUF (The Ultimate Force) is their latest one. This hardware subfamily only has one mouse thus far, and it is called the TUF Gaming M5. It's a small, ambidextrous-style mouse with very promising specifications and a decent price tag, which makes the M5 a rare bird indeed as most gaming mouse manufacturers tend to use low-quality materials for their smaller products for some reason. The M5 has main button switches rated for 50 million clicks, a PixArt PAW3327 optical sensor (with a maximum resolution of 6,200 CPI), and, of course, ASUS Aura Sync RGB lighting.
