The accuracy of the advertisement was compromised or the product simply did not work properly. It was supposed to be Bluetooth compatible with my Note 20 but it didn't charge or connect to my phone and therefore didn't work properly, it works like a simple stylist and that's it. If it worked properly it would be very easy to use, but since it doesn't work I can't really comment on the ease of use. In terms of value for money, I have little trouble with any of these smart pens. for the price (roughly: $40).
