POSMA D3 GPS Cycling Bike Computer Speedometer Odometer with Navigation, ANT+ Support Strava and MapMyRide (BHR20 Heart Rate Monitor and BCB20 Speed/Cadence Sensor Bundle Option Available)

At this price point I think this computer is amazing, you could ruin/ lose several before approaching the cost of a one garmin. I find the buttons and functions intuitive enough and the directions were manageable. The unit appears to be accurate (comparing friends' ride data: shows similar speeds/elevation/dist). I have not connected any ant+ devices yet but may get a HR monitor to test that feature. You will have to install the software that comes with the device as the gps file it writes is proprietary. If you are planning to upload your workouts to Strava it does not do so directly. To upload a workout you have to use the devices' software to export a .gpx file and then upload that. I've had mixed results uploading workouts: the time stamp formatting sometimes will not allow the file to be uploaded, I do not understand why it intermittently works as there are no export options to change. There is a (lengthy) workaround to get the .gpx file formatted correctly in order to get Strava to accept it (if anyone requires it, leave a comment and I'll post my method).All in all it's a surprising good little computer with good battery life and nice features, if your looking for a device to upload to Strava there are better, but not at this price point.UPDATE 9/16/16: Had to remove 2 stars. The unit has started having more bugs; false readings and goes "lost link" if riding in a peloton of others who also have gps units. For the money, I really wanted to like this, but having a corrupted file half way through a road race is very frustrating. I've since bought a Bryton 330 for (~$120) and its amazingly good; a real Garmin slayer. Go buy that unit do not waste $40 here.

Why 2 stars: It has the potential to be a good unit, but sadly it is not that unit yet. Maybe the manufacture/distributer will read my comments and make some improvements.1. The battery is good for one trip. So far it has not gone dead on one trip. It however is dead shortly after starting up the second day even after a very short trip. I like to ride a lot, this is a big short coming for me.2. There do not seem to be any optional equipment available. I asked the question to Amazon about heartrate, cadence add on. Amazons reply was no one replied.3. I cannot find any instructions to add the info to map my walk or Strava. It might be somewhere but I have not found it.4. The GPS mileage seems to be off. I have checked it against May my Walk and other fellow riders. A half mile difference on 30 mile is not uncommon.5. I have changed my unit to mileage and pounds. The wind velocity still shows KMH.The unit is priced right, but it needs to be better. It needs to deliver on its advertised capabilities. The seller needs to list items that work with the unit.

It is not what's advertised, it has no sensors the information on it is very innacurate when cycling, the software is terribly written and half the 'featires' on it don't work.

The hardware is good quality, however the firmware has a number of issues.1. If you delete a workfile from your PC (Windows 10) while tethered via USB the file disappears, but the space is not returned to free space. Therefor can only clean up old files from the file menu on the device.2. The user manual is not clear. Example Setting start altitude, the options other than "manual" don't make sense.3. Issues up-loading rides to Strava.4. Many ease of use issues. Still on device software / firmware v 0.015. No website for support and updates6. Slope of road, very slow to respond to changes.

Le GPS fait son job, à savoir tracer les données d'un trajet.Pour le prix c'est imbattable.Points négatifs:- le format des données est propriétaire, mais on trouve des convertisseurssur le net vers des formats standards (gpx)- le logiciel PC est pas top, et uniquement sous windows, sous mac ou linux on peut s'en tirer avec une machine virtuelle.- pas de support : le GPS propose une option pour mettre à jour le firmware, encore faut-il pouvoir trouver le site du constructeur ...Point bonus :- le support est compatible des supports garminBref un GPS simple, efficace avec un très bon rapport qualité prix.

Coge señal con rapidez, y es preciso, pero,Es un poco incomodo moverse por los menus, es complicado establecer la altura inicial, es complicado pasar las actividades a aplicaciones tipo strava, endomondo ....Con unas mejoras de software podría estar bien.Tras bastante tiempo con el finalmente me he comprado un garmin, mucho mas caro, pero puedo utilizarlo con comodidad.

Perfetto! Risolto il fastidio di fili, trasmettitori etc, etc, con il gps misura praticamente tutto! Anche la pendenza ed in più si possono condividere i dati in rete.

El GPS funciona excelentemente, tanto en precisión como en información.Faltan algunos detalles: idioma español y velocidad media. Sería sobresaliente si pudieran verse los caminos o un mapa.

This is a typical product that makes what they promise by a lower price.+ Good display+ Menus+ Easy to operate+ Battery life- Software for the PC could be betterVerdict: For those that are not branded guided or "made in" addicted this probably is a product to think. Basically the other market products are made in the same place China or Taiwan (land of semiconductors).

Funziona benissimo. Fa tutto quello che promette e nonostante le istruzioni in inglese il funzionamento è semplice. Ottimo rapporto qualità prezzo.

Devo dire che è un buon prodotto.Lo uso quotidianamente , ormai con disinvoltura, anche se bisogna studiarsi le istruzioni.(solo inglese giapponese e cinese).Si monta velocemente . Buon rapporto qualità prezzo.

Great computer for the price! Can upload to Strava with little effort. One bad thing, a small issue with one ride, it tracked me doing 22000 kms at 1500 plus hours. Fiveone-1 Stava-0. LOL.Keep on keepin' on Roadies..

It's ok but there's no firmware updates it doesn't pair with my Bluetooth sensors I wouldn't buy it again the seller needs to give more info on the product.

Ich habe dieses Gerät erst einen Tag und habe es noch nicht für eine längere Tour genutzt, ich möchte jedoch meine ersten Eindrücke hier schon niederschreiben.Positiv:+ Wertiges Gehäuse+ Display unter direktem Sonnenlicht ablesbar+ Hintergrundbeleuchtung für Display+ Ausreichend Speicher (aber nur 7 MB)+ Bedienung Funktioniert nach etwas Eingewöhnung sehr gut+ Gute AnleitungNegativ:- Anleitung beschränkt sich auf Gerät und enthält nichts zur Software (PDF für Software enthalten aber unvollständig)- Mitgelieferte Software Instabil und unhandlich zu bedienen (empfehle sie nur für Routen Export und Import zu benutzen)- proprietäres Routenformat (Unterstütz werden aber mit Hilfe der Computersoftware: Import: GPX, Export: GPX, KML, NMEA, CSV)- GPS Ungenauigkeit bei Routen (20-50m)Keine Aussagen kann ich bisher machen zu:# Ant+ funktionalität (da ich derzeit keine Ant+ Sensoren besitze)# Akkulaufzeit

Ottimo prodotto, completo di tutte le informazioni (es: altimetro con la percentuale della pendenza) funziona benissimo ed è di facile lettura,...unico neo non è previsto il menu in lingua italiana
