What is the opinion of Reddit about the
Multi-Device Bluetooth Keyboard for Mac OS/Windows/iOS/Android, seenda Rechargeable Slim Compact 2.4G Wireless Keyboard Dual Mode Keyboard with Number Pad Connect Up to 3 Devices?

Wireless and bluetooth keyboard: $10. used about 2 months before we upgraded to a new laptop so no longer need. It can connect to 3 different devices at the same time and you press an assigned key to switch between them (its really cool TBH). USB dongle and 2 seperate bluetooth devices can be connected.
