Review on Dell Premium Active Pen PN579X Stylus Black: Sleek and Lightweight for Enhanced Digital Precision by Brad Mastermind

I really like this pen, but sometimes it skips/writes "wavy", I don't know why. When this happens, I try switching programs (by holding both sides of the button) and programming again. Sometimes it works, mostly not. Doesn't happen often, but can be annoying. I don't think the battery is low, but it's also confusing. My laptop says it's 87% charged, but then I get a notification that the battery isn't low and the pen starts to jump. Then when I turn on the computer, disconnect and reconnect the stylus, or something like that, it works fine and doesn't say the battery is low anymore. I have used it one day in the last 1.5 months and have not changed the battery
