Review on 🚴 DINOKA Waterproof Wireless Bicycle Bike Computer with Speedometer, Odometer, and LCD Backlight Display – Multi-Function Cycling Companion by Toki Louton

This little thing is amazing! The backlight only works at certain times of the night and depends on the exact setting of the clock function. The radio range works flawlessly and the computer wakes up immediately at the slightest physical vibration in the recipient's brain. There are no buttons to press to wake up the system. Just get on the bike and ride, it will do the rest. Calibration is very simple and easy once you get the wheel circumference in millimeters. Very accurate and sensitive signaling unit. Everything works great and spare batteries are included. For the price unbeatable!
