Garnick Bike Computer, Outdoor Cycling Waterproof Bike Speedometer Bicycle AccessoryThis product is listed under the name GARNICK but the product that arrived was the SunDING unit.I bought the SunDING and it arrived in fully working condition, very happy with that seller and product.First, this unit is not labeled GARNICK, it is a SunDING unit.I bought this unit for the temperature monitor, and the mileage (distance) display. The clock, count up and count downwere all pluses.The setup is fully programmable, including 12/24 hour on clock and C/F on temperature.The instructions are not totally clear, but if you study it, and I mean study the instructions, you can figure most of it out. it preforms well.It does default at 2080 circ,The case is plastic and the buttons work surprisingly well for such a low price unit.The case is water proof (and this is verified as I was caught in a rain storm while riding).The display is exactly what you see in the ad and can be seen rather easily.It uses a CR2032 battery, which is included.The back light is really good, you can see the digits easily when the light is on.The sensor is mounted with a simple system with ties and the magnet clamps on the spokewire.The mounting shoe (for the Computer) mounts just as easily to the handlebar.You should be up and running in 5 to 10 minutes. I recommend this unit called the Garnick ( but is actually a SunDING.) bicycle computer.I do not know this seller nor did I get any money or product for my random review.230817 0703
