I use this with my MacBook to speed up number inputing. Really good numeric keypad.

A little clunky I found

The product is clunky, does not come with usb-c charging, only micro-b and the device is slow to wake up.

Excellent for portability - small slim with excellent battery life. Although there is a small delay once it goes into sleep mode, it still captures and outputs all the buttons pressed so it doesn't interrupt flow. Would be nicer if it could be paired to more than one PC though.
