This is easy to use. All you need to do is to plug in the USB cable into your PC and it'll recognize as an enter key.
This button itself is made out of soft sponge material so when you get tired, you can even use it as a pillow and take a nap on it!
And when you're feeling stressed out, you can smash on it as hard as you can without fearing of breaking your keyboard!
