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

Product arrived on time. Installation was easy, even though I found the instructions a bit fuzzy, but I've installed enough of these to figure it out.I haven't had a real chance to try it but it seems accurate enough and the buttons are easy to use even with bike gloves on. Very happy with my purchase.15Nov2021 follow up. When I received the product I also received a coupon that stated that if I gave a positive review, I would either receive a $10.00 gift card or a few bicycle light. I wrote the review, and I stand by it but I've had to jump through hoop after hoop trying to redeem the coupon for the gift certificate. They asked multiple times for me to supply the link to the review, a screen shot, several times and they have yet to honor their coupon. Buy something else, don't do business with liars.
