Lenovo USI Stylus Pen, Chrome OS Support, 4,096 Levels of Pressure Sensitivity, 150 Days Battery Life, AAAA Battery, Works with Chromebook, GX81B10212,Grey

***************************************UPDATE 6/20/22********************************************It's been a month of using this stylus and I'm still enjoying it. By now, I have indeed experienced the issue of hypersensitivity with regards to the nib (the stylus registering marks even though it's still about 1-2 cm away from the screen). It's happened about 4-5 times so far in the last 30 days. The good news is it's a very easy fix -- just remove the battery, reinsert it and the stylus will go back to normal.As for battery life, I'm still using the original battery with about 1-3 hours of daily usage for the last month. So the battery life thus far has matched my expectations.***************************************************************************************************************Seeing all the negative 1-star reviews, I decided to put in my 2 cents. I've been using this stylus for a total of about 40 hours now and I have to say -- it's well worth the money. With regards to the more popular styluses (Surface Pen, Apple Pencil, Samsung S-Pen) it offers near-parallel quality in terms of writing and lack of latency, although it doesn't offer some of their features (buttons on the stylus or an eraser feature). But at 1/2 to 1/3 of the cost of those others, the value is obvious and quite understated.Now the caveats. The latency will greatly depend on the app you're using. For note taking, PDF marking, and light drawing I use "Squid" and the latency is virtually nonexistent. For more intricate drawing, I use "Concepts," "Click Studio" and "Sketchbook by Autodesk." The latency on Sketchbook is noticeable (though not inhibiting), but Concepts and Click Studio have the same negligible latency as Squid. These applications make this stylus a dream to work with.The quality of writing will depend on the cleanliness of your screen. I found that if my screen is SUPER clean, it causes friction on the nib and makes for a very rough feel as I write. But if my screen is too inundated with smudges and fingerprints, then the nib doesn't make very good contact and skips a beat or two, causing broken lines. So I've taken to gently cleaning my screen with a microfiber cloth, but not using any cleaning solutions. This allows the nib to flow very smoothly across the screen, akin to a well working ballpoint pen.The palm rejection is great, but not perfect. After testing this on numerous apps, I think the palm rejection is related to the app being used just as much as the stylus itself. On "OneNote," the palm rejection is fairly bad. The stylus registers and makes the intended marks, but dots also keep showing up where my palm was resting. The same dots appear on most of my other apps as well, but not nearly as frequently as with OneNote. But so far the palm rejection on Squid, Concepts, Click Studio and Sketchbook has been fantastic. So overall, I'd say Lenovo still needs to work on improving the palm rejection on this stylus, but it certainly isn't a deal-breaker except for perhaps the most nitpicking of users.And lastly, I believe all the reviews regarding the hypersensitivity of the stylus (causing it to make marks while the nib is still a centimeter away) may be due to the Chromebook they're using. I've noticed every single one of those reviews was written by people using this stylus on the Lenovo Duet. It may be that the screen on that Chromebook reacts poorly with the stylus. I use the stylus with my Lenovo Flex 5i (and again, I've had absolutely zero issues regarding hypersensitivity and unwanted marks). With that said, my positive experience may also be because Lenovo has fixed the issue. I noticed the nib on my stylus is rather pronounced, hanging about 1/2 centimeter below the tip of the stylus (as opposed to the nib being flush with the tip of stylus like the pictures show). So perhaps Lenovo, since seeing/hearing about the hypersensitivity issue, has replaced all the nibs with these new ones and has resolved that problem.Whatever the case, I've had nothing but a 95% positive experience with this stylus. It's relatively cheap. It feels good to hold. It writes very smoothly with excellent pressure sensitivity. And there is no hypersensitivity as written by many others a year ago.Well worth the $35 in this Chromebooker's opinion.

The stylus worked great for about a day, but then began to register when 1/4 inch in the air. This lead to lots of unintentional dots and lines when trying to take notes rendering the stylus useless.Looking online, this is a known issue when this stylus is used on a Lenovo Chromebook. I have a Lenovo Duet 5 that I used mine on. The only help Lenovo gave was to try a different battery, which didn't resolve the issue. Removing the battery does reset the pen for a minute or two, but then it goes right back to being unusable.It seems like other people use this stylus with Chromebooks not by Lenovo and have good results. So, buy at your own risk.

No issues after 2 years of weekly use( not daily).

I bought a Lenovo Flex 5 Chromebook on Amazon Day sale and purchased this pen with it. I loved having the pen to use with it...until I lost the pen. I have no idea where it went, but I ended up having to buy a 2nd one.That said, it would be nice if a holder came with the pen to help reduce the risk of misplacing it like I did. Also, I would've liked to have seen a button on the side that you can click to where it acts like a mouse right click (on Chromebook you have to hold the pen down on the screen for a few seconds to mimic this action). I don't know about others, but holding the pen down on the screen for a few seconds just seems unnatural, and a button would've been a great opportunity for this.It's rather odd that the pen uses AAAA (you read it right, quad A batteries, not triple A), and so I bought rechargeable ones solely for the pen. Personally, I would've liked to have seen the pen use 2 AAA batteries as those are more consumer friendly, but what do I know.

I bought my Lenovo Duet 3 Chromebook several weeks ago and have been exploring its' capabilities since. Despite understanding the limitation on the display for this device that required a USI 2.0 pen and thinking I had found one, I was disappointed to find that it didn't work. Further research seemed to indicate that there was only one USI 2.0 pen on the market (this item, the LenovoUSI Pen 2) and it was out of stock on both the Lenovo store and Amazon. I received my pen today and can confirm that it works brilliantly.The accuracy and speed seem to be very good. I had little delay when testing cursive writing and drawing as well. The pressure sensitivity allows pencil drawings to be lightweight when little pressure is applied and heavyweight when higher pressure is applied. The palm recognition can take a little getting used to, but I am literally minutes into using the pen, so I'm sure it will become second nature. And the issue is nothing major, simply if the pen is lifted more than an inch or two from the screen, my palm would be interpreted as a touch and move the image. Happy note taking, drawing, and annotating fellow Duet 3 owners.

This pen was decent for the quality, and the metal casing felt durable, very smooth and comfortable to the touch, although, I bought it because it said it was compatible with my laptop, but when I tried it out, it didn’t work. If this was user error, don’t listen to me, but I would definitely reccomend looking close at the compatibility with the laptop you plan on using it with. Great product though!

First thing I'll mention is how excited I was that it worked right out of the box. I thought I had done my research prior to the purchase of another pen and well... here we are. It fits great in my hand, can clip to my spiral notebook so I don't lose it and like I stated, so far so good. I'll update if anything changes!
