Easy to use, if used in excel it requires a setting to prevent automatic cell changes. It has a slight expected delay due to being wireless, and charges with a USB cable included in the package.

You can also set the time after usage when it automatically shuts down to preserve battery life. Since I use it for data entry on a computer and I am next to the tower and its USB, I have not tested the maximum range.

The build quality is just okay, it doesn't withstand many drops, etc
