Review on 🚴 MEILAN M3 Mini GPS Bike Computer - Wireless Bike Odometer & Speedometer | Waterproof Cycling Computer with LCD Backlight Display for Men, Women, Teens | Outdoor Cycling Essential by Gary Shakeone

Okay so I picked up this idea from others and wanted to see if these mini bike GPS devices for RC speed racing would work/accurate. This is a summary and important things to know: - Accuracy is good. I compared it to my SkyRC GNSS (GSM020). I had 54 mph (GPS minicycle) vs 55 mph BUT HERE'S THE IMPORTANT PART. Sometimes it takes a few minutes to find the saturation signal (sometimes longer). It also takes a long time to register the speed value (slow refresh rate). Unlike more expensive speedometers, this GPS only measures speed once every 1-2 seconds (versus more than 10 times per second on other devices). I know this because I did some tests. This means you have to hold the top speed longer and potentially have a much longer road/area. Even from a stop does not show the speed of a second 3-5 The block is smaller but not small like the others. Also, the speed reset button is on the back, so sometimes it's inconvenient to remove it from the car/truck, then reset it, and then reinstall it. Attachment options: You can use the special "rubber bands" or Velcro fasteners supplied. .If this GPS was more expensive I would give it a lower rating, but since it's quite affordable (compared to other RC speedometers) and since it's proven to be accurate (if it wasn't accurate, it's going to be a big one star deduction). So I would recommend it as an inexpensive way to find out the speed of your RC. Just make sure you understand the limitations. Review (if that's all you read). It's less expensive and accurate, but requires longer runways and the refresh rate is slow. Slightly larger than other devices, but still easy to assemble. The reset button is not in a suitable place, the signal is sometimes "locked” for a long time. All in all, this is a good budget buy. Would buy again if a smaller budget is needed. Just understand its limitations. Hope that helps
