This clip helped me repair a bad wheel on a bike I bought as a gift recently.  The price was reduced because the wheels were bent.  So I did some googling and decided to risk buying the damaged goods.  It paid off.  Here’s the video that helped the most: 

Lately I’ve been overrun with spam calls.  This free app saved the day.  Community members upload ratings after they receive calls from friends, family, and telemarketers.  Phone numbers get ranked positive, negative, and neutral.  You can automatically block negative rated calls and unlisted numbers.  I was receiving up to 25 unsolicited calls a day.  I’m down to fewer than 5 a day getting through.  This app is a major improvement.  Be sure to do your part and upload ratings too.  If we all work together, we can eliminate nuisance calls.  The project is supported by donations.  Here’s a link to the main page: https://www.shouldianswer.com/
