Review on CYCPLUS Bike Computer with GPS and Wireless Connectivity, Backlight for Night Riding, Waterproof Speedometer Odometer, Extended Battery Life, Enhanced Professional Data Analysis by Scott Rodriguez

I use it as a speedometer and odometer on my 1925 Ford Model T and it works well in this application. The T models weren't made with either tooling and this solves that problem nicely. It's tiny and I used industrial grade double sided tape to attach it to the dash with the included bracket. To charge, I simply unscrew it from the mount and connect it with the cable that came with it. I disabled it to save battery when I stop. This worked for a full day of the tour. It appears accurate and is easy to read in daylight. The instructions are not too complicated.
