I use this in my work doing data analysis and coding. It's extremely helpful as my MacBook doesn't have the numberic pad that is so helpful in speeding up this process. I've purchased one for work and one for home. It reduces the strain on my hands and is a simple plug in and type. The buttons are very responsive and comfortable to use.
