Review on JGRZF Bike Computer: Wireless Speedometer and Odometer with Backlight, Waterproof LCD Display – Ideal for Outdoor Cycling and Fitness (Wireless Computer) by Bill Kodba

Please contact me for warranty. I have had this device for two months today. This worked very well for the first five weeks. Then the main unit started to stop syncing with the connector mount. I've fixed bugs including replacing all the batteries, removing and reinstalling everything. It works for a few miles, and then suddenly it stops working. The next time he runs a few kilometers and then stops again. After a few rides it works perfectly. And then I can't start other attractions at all. UPDATE - The seller refunded my money for the purchase. They answered and backed with a guarantee - not everything is so bad.
