Nice

Waste of money. Doesn’t work. I’m so annoyed with this pen.

This "LiXiongBao USI 1.0 Pen for Lenovo Chromebook" works great with my DELL 5430 Chromebook. From internet searching and my best-guessing, the Dell 5430 Chromebook appears to support a USI 2.0 compatible stylus. But USI 2.0 is generally compatible with USI 1.0 it is just that additional features that 2.0 provides might not be available in a 1.0 type stylus (from what i could best understand.) But regardless, just slip the AAAA battery into the stylus and start using it. No pairing or anything more complex to do other than to start using it. (And the quad-A battery comes with it, even.) Of course, since there are a ton of different stylus protocols out there, if your notebook/laptop/Chromebook does not support a USI-type stylus, you could well encounter issues. So do your research first to avoid disappointment.

Doesn't work at all

Title says it all. This USI pen certainly does the job, and also seems to work nicely on my HP 360 Chromebook as a bonus!

Works just the same as the Lenovo USI 1.0 pen, feels better at a fraction of the price. For anyone having issues with it, double check your Lenovo Chromebook actually supports this style of pen, or a pen at all. Just because it has touch doesn't mean it supports a pen.
