Es verdaderamente complicado la programacion inicial, ya que lo logras funciona mas solo te informa lo basico y es poco amigable su usoMas pequeño de lo que imaginaba

First one was damaged, one of the buttons would not work, was shipped a replacement the next day and it works great.

I had 2 earlier white M3 Meilan units purchased in 2020 that worked well for approximately 2 years, then 1 suffered a meltdown that using the recessed reset button couldn't cure.I purchased another M3 in early 2022. The M3 has only 2 buttons for shifting modes, so they require holding the buttons down longer or shorter to get in different modes or to accept or eliminate data. This is cumbersome at best, but with my newer unit, I have learned what to do and not do to reset and record mileage.I have also learned not to play with it during a ride, since pressing too long or short or pressing the wrong button may require calling up the manual on your phone and spending 20 minutes computering, not riding.I learned that the more expensive Meilan M1 actually records your altitude profile, while the $30 Meilan M3 gives an instantaneous altitude reading. Meilan has an M2 unit that is slightly larger and does more (things like cadence and heart rate with bluetooth, and a Blade model and an M4 model that are larger still and have buttons on top of the unit. All are priced $56. The next level is $100+ for the M1 and Finder models that both offer navigation via smartphone app, plus all of the other optional things like power meter, hr, cadence etc..The Positives: I like the use of GPS to provide speed , mileage and altitude data, without having wires or a remote wireless sensor with separate battery, that can go bad. Admittedly, when cycling under trees, your GPS speed reading will read low. Interestingly, Meilan's higher priced units with cadence and speed go back to using remote sensors with batteries and sending units. This is great for those who approach riding and personal fitness as a scientific project. I was a scientist for 43 years and I ride to get away from charts and graphs. The M3 has just the basics. Also, the unit seems to have the battery power for a hundred mile day before recharging, at least when new. It can be carried in your pocket to record length of hikes and dog walks, and can provide paddling speed or sailing speed. What other bike computer can do that? And the cost is not hundreds, but $30. They have also improved their mount, such that the earlier units could only be mounted on the handlebar, but now can be mounted on bar or stem. When turned on, It can take a half to 3/4 mile to acquire the GPS signal, if you begin riding immediately. You can, of course, turn it on first and give it a few minutes to acquire signal before riding. Conclusion: For its' size and price and general reliability, plus its ability to be used for hiking and paddling, and even model car and aircraft racing, if you can put up with its' funky short press, long press, left button, right button navigation, it is an amazing little unit! (My first mileage recorder was a small mechanical box that mounted to the wheel hub, with a star shaped extension that a peg mounted on your wheel would hit and move with every turn of your wheel. So many hits against the star would indicate a mile. Amazing how far we have come since 1977!)

This little GPS bike computer functions very well for telling me my basic needs for speed, altitude and odometer. It seems fast to react to speed changes and locks quick to satellites. But there are a few issues with the design that should be improved:1) The handlebar mount is terrible. It's a Garmin connector thank goodness so I can use another mount I already have that is much more solid. The one that it comes with has flat cheap rubber bands and moves all over the handle bars when touching any buttons.2) Charging. It's Micro-USB which I have nothing of any more. My bike headlight and tail light, phone, speaker etc... are all USB-C. I really don't want anymore cables to carry. I'd be happy to pay $10 more for a USB-C version.3) The charging port cover. It's really small, tight and deep, in the way of getting a cable plugged in easily. It's mounted too close to the Garmin connection directly on the bottom. If they moved it forward a quarter inch I could leave it mounted while charging it. Instead every couple weeks I will be removing it for charging which will wear out that plastic mount connection prematurely. The stock mount works better for charging while mounted but it's not workable for me. I wont deal with repositioning the mount each time I turn it on.Otherwise I like the basic functions after taking it on a ride. The LED notification light is a smart design for satellite connections and battery life. Nice to see a proper use of red, yellow and green that follows international recognition. Too many things now have blue for battery charge and "good or full" connection which is just confusing to break from standards. Green always means GO or FULL so great to see that on this MEILAN M3 Mini GPS! Having the backlight that will stay on permanently is great as I ride in the evening from work daily. I wish the back light could be dimmer though as in really dark trails its distracting to my peripheral vision.

My Yamaha motorscooter has a speedometer that is difficult to read because of reflections off the glass face. I added this GPS speedometer, it is much easier to read. When you get yours, do not turn it on until you read the directions. It boots up in setup mode and will walk you through the setup the first time it is turned on. If you turn it on and punch a few buttons, like I did, setup will be frustrating. There is a factory reset button on the back. Hit that and like any computer thing (or vending machine), keep punching buttons untill you get what you want. Once you get there the spedometer will work fine. I don't use any of the other functions so you are on your own for them.
