    Yeah, I instinctively tried to open mine with vinyl gloves on once and immediately thought “I’m dumb, gotta take these gloves off first.” That was a good shock when it actually worked first try, much confusion…

      It makes sense if you think about it, ultrasonic vibrations will “see through” the glove and detect the finger ridges beyond. If the glove is scrunched up, it “looks” like finger ridges that aren’t yours, which will then not match.
