Review: Recomend! - works quite nicely with the lenovo yoga 520 series, does the job its required to do. Yes it does sometimes leave space btw lines when your making a straight line but really rarely id say on 10,000 lines once. And it also might be because of the pressure its unknown to be honest. Overall amazing pen. I do recomend it. Its pricy but worth it in the long process.
Review: Been using it non stop! - Great device, very intuitive! Ergonomic, great to hold and quite natural in the hand, which I was surprised about! Easy to set up and to use, was able to begin drawing away in seconds. Love the fact that the pen can be customized so that the buttons serve the functions the user requires, although this does depend on the software or application as I downloaded a drawing app that doesn't respect my button choices but it seems to work perfectly well with the rest of my computer. The included Wacom application enabled me to set up the pen's pressure sensitivity quickly and made the overall calibration process very swift and easy. The app is also quite helpful as it lets me see how much battery is left on the pen. Found the USB holder rather helpful as it keeps the pen close, and being able to place the pen in 2 different positions depending on what I might be doing with it at the time was equally handy. Palm rejection is a treat and greatly appreciated, although sometimes you need to hover the pen slightly above the screen before you start using it so that your computer registers the device and therefore disables its normal touchscreen function. Although I appreciate the battery being included, wished Lenovo had come up with a rechargeable option. I use a Lenovo 720

### ⭐⭐⭐⭐ have a problem
*by D***G on 17 July 2021*

As far as I can tell this is a good product. But I do have one problem which I don't think is a problem with the pen but with my Lenovo duet. The problem is the duet won't let me use the pen to make notes. It lets me do the other things, magnifying glass etc. but not notes. If I go into settings it says no note keeping app available but chromebooks have Keep which is a note taking app. I have googled this but no-one seems to have an explanation. So I would advise checking on your chromebook first before you buy this because I imagine the note taking feature is what most people will want it for.
