Review on 🚴 CYCPLUS M1: Waterproof ANT+ Wireless GPS Bike Computer with LCD Display and Backlight - Perfect for Tracking Speed and Distance on Your Bicycle by Shawn Sims

What this bike computer does well, it does very well: The screen is large and easy to read, even for those of us who have presbyopia (need reading glasses). - Battery life is good and should last a couple of weeks on a single charge. - I've had no trouble connecting to satellites in under a minute and haven't lost them yet. - It's as accurate as possible. As a distance as shown in the picture, it's within about 1/2 percent of my wired computer after a 40 mile ride. This means that a wheel hub sensor can be dispensed with. There was no problem connecting my standard heart rate monitor. The backlight works well and makes the screen easier to read at night. However, there are some significant disappointments. Computer: - The odometer cannot be preset, so it starts from zero. - Drive time only has two units, so starts at minutes and seconds, but then changes to hours and minutes an hour later, dropping seconds. - The incline function is unstable and unstable even when driving on a stable slope. - The device rattles, so it can be noisy on a bumpy road. - The clock displays 24-hour AM/PM format instead of 12-hour format. I highly recommend this computer if disappointments don't matter. But for me they are, so I can only give three stars.
