I bought it because the keyboard of my laptop died and I wanted a product that is small enough while keeping all the advantages of a keyboard with numeric pad. It is exactly the same width as my 15.6 ". The keys are noisier than a hair keyboard laptop but that's normal for a very convenient price.
Just a detail that napparaît not often, by pressing a button, the keyboard sometimes gets carried and continues to write the key to infiniiiiiiiiiiiiiiii like this without the key is stuck. This is very rare.
Small disappointment, the keyboard is black and not with print as the picture shows.
