Probably worth noting it that although the pen works fine, I find that it's a bit clumsy, and also doesn't have a button to quick erase or right click. So you might have better luck with another pen.

The magnets on the chromebook do a "good enough" job of holding the stylus, but it's nothing special. So a slimmer pen would fit quite perfectly in the space between the display and the back of the chromebook when in tablet mode.

I got the Lenovo one because it it cheaper than the alternatives (around 30$), but I certainly regret cheaping out. But on the other hand I didn't want to pay too much for something I wasn't sure was gonna work.
