This is my second purchase of this pen. Found the first one very useful on both my Samsung Galaxy smartphone and my ipad. Not the most responsive but good enough for selecting text and other small details on screen.The pen is OK. Doesn't work on standard applications in Lenovo C330 workbook. I wanted to take notes with it in Google docs and it doesn't allow this function. I wish it did.The touchscreen works on my phone and my tablet but the accuracy is the real problem. When writing notes on my tablet the pen makes my handwriting illegible and it’s significantly worse than my first pen that I hadMy son wanted a thinner stylus for his school work. This works well for him he just had to get used to not touching the screen while writing.I ordered this pencil because it popped up with the laptop as a bundle. I had never heard of it and looked at reviews and decided to buy. My laptop is still being shipped but I’m using it on my iPad and love it! It is great! So long as it lasts. I recommend this pencil, it’s really great!Nothing special about this in my opinion. It really just seems like a normal stylus pen and nothing special about itIt has a nice weight to it. It does work on touch screen, however, using notes and drawing apps so far it's pretty jumpy every so often.I have only used this product a few times, but it works great and hope to be able to use more.Unfortunately this does not work very well for the Lenovo Flex 5, 2-1 Chromebook for which Amazon suggested it as a good companion purchase. The thick end works fine however the pointy end completely misses most of my input rendering it useless. Works just fine on my Surface pro laptop but I already have a perfectly good stylus for this so that's very little value add. Careful with compatibility folks.The supplied charging cable does not fit the charging portAlso not sure what kind of port this as I have so many micro usb cables and ne of them fit !The pencil is not useful at all.Works good as advertised
