I ended up returning this only because I decided to buy the Aula f99 with the 10 key. Otherwise I would have kept it, the keycaps felt great when I tried it out. I was excited about the swappable keys too. If I had kept it I would have changed it to match my TKL.Maybe in the future I'll get it again if I ever switch back to my TKL keyboard. You live and you learn.

The larger keys make it easier to use by touch. I plug the dongle into my displaylink dock and it works well with my Mac.There’s no warning when it needs charging. One charge seems to last several weeks depending on use.

No es malo pero ni siquiera tiene un compartimento para poder guardar el USB de 2.4 ghz, la aplicación que ponen en los comentarios de la venta no funciona hay que buscar otra de una marca distinta para poder usarlo con el software de la computadora.

Could not get the Bluetooth option to work, wir d mode works fine, but when I unplugged the USB dongle (this happened twice), it caused a Driver Power State Failure and blue screened my computer. Returning immediately and scanning the PC for viruses.

Works well. Connects easily both corded and Bluetooth. Nice to have a standalone num pad if you are using a ten key-less keyboard regularly.

If you like the clickety clack sound of keyboards, this is a nice little numpad. Good connection and cute color.

I bought this so I could switch between my work PC and my home PC over Bluetooth. It works well on my work machine but interferes with my home PCs Bluetooth connection and the music stutters constantly. Luckily it had a RF receiver that I could use.
