There are plenty of wireless keyboards that incorporate an easy access volume knob, but Seenda’s MOU-302 is one of the first wireless mice to include the convenience. That’s significantly cheaper than alternatives like Logitech’s $119.99 MX Vertical and its $79.99 Lift mouse which ditches a rechargeable battery for a single AA.

The dedicated DPI button lets you toggle between 1,000, 1,600, and 2,400 DPI settings, making the mouse potentially useful for gaming. Seenda claims the mouse’s primary left and right buttons offer “noiseless clicking.”The primary buttons and scroll wheel on the mouse are angled 57-degrees so it can be held and operated more ergonomically.
