Cooler Master is perhaps best known for its fans, power supplies, and other internal PC hardware, but the company also sells external accessories. The Cooler Master MM720 was released last year as an incredibly lightweight mouse, at just 49 grams, with a starting price of $50. Now you can buy one from Amazon-owned Woot for $30 (opens in new tab).
This is a lightweight mouse with the same honeycomb-like design we've seen in a few other mice recently — it reduces the mouse's weight by nearly half while retaining the same structural support. The cable is also lightweight, and the built-in sensor is adjustable up to 32,000 DPI.
Cooler Master MM720 | 32000 DPI | $29.99 (save $19) (opens in new tab)
This lightweight mouse is currently on sale at Amazon-owned Woot.com for $30, which is $19 below the usual price (opens in new tab). Amazon Prime members get free standard shipping.
The rest of the feature list is comparable to other wired mice in this price range. You can change the button mappings with Cooler Master's desktop software, the mouse feet can be easily swapped, and of course, there's a customizable RGB light on the top. The only downside is that this mouse definitely won't work for left-handed folks.
