Manufacturer description
The BT21 Baby Wireless Silent Mouse by Royche brings the TATA character from the BT21 lineup into a functional desk peripheral, and the spec sheet is more practical than the styling suggests. Silent-click switches mute the usual click noise, so you can work in a shared office, a dorm room, or a late-night stream without the clatter that a standard mouse produces. The 2.4GHz wireless link reaches 20m (66ft), far past the desk-to-laptop distances most people need, and the receiver setup keeps your USB-C ports free on a dock. Power comes from a single AA battery rather than a proprietary pack…
