Review on 🚴 CYCLESPEED Mini Bike Speedometer Odometer Wireless + Waterproof Display - Large LCD Backlight - Multi-Function Bicycle Speedometer MPH Alternative - Ideal for MTB & Road Bikes by Joshua Garris

First Impression: Good: Works as described, fairly easy to use. Easy to read. Seems accurate. Cheap. Allows me to enter my previous mileage and even my previous accumulated driving time. Bad: * This is a pretty big value. Let's see how long it lasts on my mountain bike before it gets hit by something or breaks under its own weight. * The rubber band of the mount snapped instantly (but you can use zip ties) * The transmitter's magnet can rotate on the spoke and collide the wrong way. I ended up using the magnet from my old Bell 200 because that's why it screws onto two spokes.* The transmitter is loud. It probably uses a reed switch instead of a Hall sensor, so it clicks with every turn. This can be annoying and probably won't last long.* The manual isn't very clear. For example, should I stick a "piece of rubber" to the bike or to the sensor? What is "Trip Up" and "Trip Down"? I will update this review if there are any issues in the future.
