COZY350 Bicycle Computer Wireless Bicycle Speedometer Cycling Odometer Automatic Wake-up Water Backlight Resistant Bike Computer (Silver

its perfect work well wireless water proof its the best speedometer i ever buy but its pricey and also the thing i dislike the most and find really stupid for someone who need speedometer at night is that its impossible to use it you have to push a buton for half a second and then you see speed who is freeze for you to see it but for like a second and then you need to push it again this is really stupid when you ride to have to push the button while you have to look in front and then have the speed for two second also the 8 second is in fact like 4 second or less and have to push more button for more time for real this is useless but otherwise good if theres was a lighing section for this product where you can give star i will give (0) and way more less

Put it on my bike and it did not work at all

Nice small
