Review on 🚴 DREAM SPORT Bike Computer: Waterproof 16-Function Wired Speedometer and Odometer DCY016 by David Will

If you don't know what WPOS stands for, just buy it and you will find out. First, the instructions are on a folded small sheet of paper that requires a magnifying glass. They're mostly blueprints that are hard to read, but they're pretty easy to install. After wasting an hour I just couldn't get it to work. I held it on a bike stand and couldn't read it. waste of time. I'm sick of the cheap Chinese crap they sell at Revain. I would happily walk into a bike shop, pay twice as much and buy something that actually works. Don't waste your time.
