The "phone dump" alarm is hilarious but honestly genius, way better than my method of waiting until my phone screams at me that storage is full. I had 47 pictures of the same parking spot because I kept forgetting which level I parked on, and instead of deleting the wrong guesses I just kept taking new ones. My camera roll is basically a crime scene of my bad memory. The uncheck the keepers trick is the part I never thought of, I always try to pick what to delete and end up scrolling for an hour. Ten minutes on a Sunday beats my system of panic deleting at 2 percent battery in a parking garage.

Buddy of mine bought a roll bender off a guy in a parking lot and didn't find out the bottom roll was bent until he tried to run a full length of channel through it. He now brings a short piece of his own stock and runs it through before any cash changes hands, so he can see if it tracks straight or binds up. That trick plus turning the shafts by hand to feel for slop would catch most of what bit you.
