This looks like it's the size of something you might be able to type on, but it's tiny! I was very surprised, it's about the size of a high school pocket calculator, less than 15cm across. It's also really light and feels very flimsy at first, but after using it for a while I actually really like it. The keys have a solid clicky feedback and it works perfect on Windows 10 straight out of the box. Perfect for my arcade machine admin, but you would not want to be writing a novel on it.
