Hope it works for you people as well, it has been really frustrating to have the pen working like that. Lenovo 2-in-1 Chromebook Duet 10.1 Touchscreen with Keyboard & USI Pen,4GB RAM,128GB eMMC, MediaTek Helio P60T ZA6F0075US. This will also remove some of the pressure on the battery, and again the pen will be less sensitive. If the pen gets too sensitive again, without removing entirely the battery cap, just unscrew a couple of mm the cap.

Remove the cap and try to push the spring towards the inside of it (compressing it), this will remove a bit the pressure that the spring later does on the battery, when you screw the cap back on. So I just tried two things that seem to solve the issue: Simply put, this device is a USI 2.0 Chromebook, and while that brings some cool upgrades like better tilt support and wireless charging, it also means support for in-cell displays. I think I just found the reason, being that the spring in the cap is pressing the battery too strongly (even if it sounds weird, maybe somebody could explain why would that be the case).

This makes the pen, even when it's being hold several mm away from the screen (not touching it), unusable in many cases. It said it would ship in 1-2 days but it was 7 weeks and way after Christmas so I had to buy a cheap stylus to hold her over until this one finally arrived in mid/late January.Sometimes it happens that the USI pen, that is supposed to work with the lenovo duet becomes overly sensitive (presumably also affecting the battery). So far, no regrets other than it did take over 2 months to get the stylus. I bought her a samsung laptop then realized it wouldn't work for drawing so I ended up returning it and buying the Chrome tablet 10e and this stylus. Hopefully the batteries will last a long time. There's just no point putting it in there and making it so hard to remove that you risk breaking the pen. I had to Google a YouTube video and the guy actually popped the spring out trying to remove the tag from his. It would have been nice if there we're instructions because I didn't know if it was supposed to be removed or not and it was really stuck in there.

The only annoying thing was the tag inside where the batteries go. Easy to use & works perfectly Great stylus! It really does make all the difference when drawing and writing on a tablet! It's so easy anyone can use it because you literally don't have to do anything except pick it up and start drawing.
