I believe vacuum holders are predatory products preying on people with OCD.
Ask any commercial photographer who shot tabletop, jewelry, etc. regarding tape and film bowing. Remember that sometimes you'd leave the loaded holder in the camera for several minutes while doing multiple pops and you don't want the film moving. Perhaps some other crusty half-dead geezer could rise from the depths and give me a confirmatory slap across the nether area of my body that used to be functional before the maggots ate it away.
