Review on YS Wireless Waterproof Bicycle Speedometer & Odometer With LCD Display & Multi-Functions - Track Your Ride! by David Strawn

The SY bicycle speedometer and odometer looked good at the start. I was able to install it despite poor instructions. (Steps out of order, poorly described and no ability to see what the screens are supposed to look like.) I couldn't set the time on the unit but tried it on my bike and except for no time capability, it worked. Tried multiple times to reprogram it but it kept skipping the time setup screen. I e-mailed the vendor 3 times: responses were 1. follow instructions, 2. no-audio video that didn't show anything I didn't already know EXCEPT it stopped at the time setup screen on their unit. 3. No response to my 3rd statement describing what I was encountering. Not knowing how long you've been riding is an important part of the exercise tracking process so this is useless as is.
