Good only if you don't need it!

Only works for small people and skinny tires. If you are a bike racer, why bother? You already have a team mechanic to figure out your tire pressure!

Meh. Useless.

Largest tire is 32, doesn't account for tubeless, tire TPI, road surface. Get an accurate gauge and a China marker, try different pressures, write them on the tire sidewall. Use the one you like best.
