Review on 🚴 POSMA D3 GPS Cycling Bike Computer Speedometer Odometer with Navigation and ANT+ Support - Strava and MapMyRide Compatible (BHR20 Heart Rate Monitor and BCB20 Speed/Cadence Sensor Bundle Option Available) by Jacki Beauchene

Why 2 stars: It has the potential to be a good device, but unfortunately it's not quite the device yet. Maybe the manufacturer/distributor will read my comments and make some improvements.1. The battery lasts for one trip. Until I died on a trip. However, he died shortly after launch on the second day, even after a very short voyage. I like to travel a lot, for me this is a big disadvantage.2. There doesn't seem to be any additional hardware. I asked Revane a heart rate question and added cadence. Revains response was that no one answered.3. I can't find instructions on how to add information to my walk or Strava card. Maybe there is somewhere, but I didn't find it.4. GPS mileage appears to be off. I tested it on May my Walk and other riders. A difference of half a mile over 30 miles is not uncommon.5. I changed the unit of measure to kilometers and pounds. The wind speed is still showing KMH. The device is priced right, but should be better. He must realize the declared abilities. The seller must list the items that work with the device.
