Review on 🖊️ SyPen 3-in-1 Stylus Pen with LED Flashlight, Ballpoint Ink - Green, 6PK by Simo Whisperer

Got them as a gift for a group of 12 boys. I bought three packs so they can choose the color they like. In each pack, the silver one didn't work. It was awkward at the party. I guess the silver ones don't work randomly. It was a battery problem. Each runs on three button cell batteries. I took out the batteries, swapped them out and put them back in and now the light works fine. I like them because they aren't too bright in case you have to get up in the middle of the night and don't want to wake your wife. You look good. The pen part works fine. How difficult will it be to make sure the light is working before it goes out?
