XOSS Sprint Cycling Computer, GPS Wireless Cycle Computer Bike Speed and Cadence Sensor (1 XOSS Sprint)

Buggy and frustrating software.Impossible to set up time. There's only one option to set time: synchronize to phone's time zone - did that and it shows 1 hour more that what it should. Allowing good GPS reception and syncing time zone again did not fix it.Power meter cannot record both right and left pedal so no power balance. That's why I bought it ... ugh.Maps cannot be transferred wirelessly. But I need to go all the way through selecting maps and trying to download them to get some fuzzy warning about wireless data being expensive and stopping me from getting the maps because I don't have a usb connection to a PC. Ummm ... what?The thin manual is almost useless.Too bad because the hardware seems ok and the display is fine even in the sun - but the software is just not ready.There is potential in this device, after a few more years of work improving the SW.As for now, look elsewhere.[Edit, 8 Aug 2020]- GPS is of horrible quality: a few trees around make reception unreliable and going through woods means no reception at all - so unusable in woods. Acquiring satellites took >10 minutes this morning!- When starting a ride after acquiring satellites it immediately starts logging without any other "start" dialogue, which makes me miss the start every ride!! So the statistics of the ride are unreliable, every single time, by design! My Amazfit Bip watch asks for starting the ride after acquiring GPS.- It doesn't seem to have a barometric sensor, as claimed, or the software doesn't use it. Altitude freezes whenever GPS reception drops, which should not happen if really using a barometric sensor. Slope grade jumps all the time, as if it's based on rough altitude data from gps - if using a real barometric sensor it would have been smooth/stable.[Edit, 26 Sep 2020]Battery holds for ~2h, not even enough to go through one ride.Just bought a Bryton 320 - whoa! All features work perfectly including barometer, gps, hr, power meter with left-right balance, screen customization, battery, etc.The XOSS goes where it belongs - to the trash bin.

I have had this bike computer for four months now. The first one that was sent to me when I tried to upgrade it some how corrupted the memory and would not allow me to store any files, maps, or even store a ride on it so I had to send it back.The new one is working just fine even after the upgrade. It is working with no problems. I have stored all my rides on it totaling a little over 500km's and uploaded them to Strava with no problems. I have created maps for rides and it does give you turn by turn navigation. You can also create maps for rides using other tools like the one in Strava. The only down side that I have with it is that the map doesn't orient to the direction in which you are going. I have speed, cadence, and heart rate sensors connected and working fine.Update 03/14/2020After using the XOSS Sprint now for a while it is a good cheap bike computer. It is not better then the Garmin or the Wahoo but for the money it is a very useful. The functionality and option work well and the screen is of good quality. This device is good for beginner riders to learn on and for the weekend riders to now get lost. With the last update to the app you can synchronize you rides to Strava and Trainingpeaks easier.

I wanted a wireless computer to connect my sensors with as using my phone wasn't the best solution. The computer connected to both my HR monitor and my Cadence through ANT. I think the HR monitor was more accurate than when using Bluetooth on my phone. All in the computer is pretty nifty. The only issue so far has been the initial firmware update. It got stuck at 31% and I had to disconnect it reconnect and start over on the app. I was scared I bricked it, but it seemed to of worked fine. The GPS speed is a little wonky in areas because of tree cover, but I am getting a speed sensor Saturday so I have as accurate of data as possible. All in its a good buy for $100 from capability to design. If I run into any issues I will update.

Has a lot of potential! Unfortunately if you want it to give Imperial measurements, mine would only give MPH for the current speed. Distance was still in Km!! Also all the recorded ride data was metric! Really nice product if you use metric... I couldn’t get the route import page to work, as another reviewer noted. I feel it needs more development.

Not worth the hassle. When it works, life is good. It rarely works. Drops connections regularly, which requires a reset. But you can't use it after a reset until you re-pair it with a phone. Route builder/uploader is either buggy or broken, depending on the day. Recently, it's started giving erroneous measurements, like speeds of 1400mph. Happens with multiple reconnected sensors and persists after resets. Just... not worth the hassle.

This product has promise. It looks like it should be really good and useful. But the speed and distance are way off (compared to stats from my iphone). It is approximately 40% off. I tried the speed sensor, then tried relying on GPS. Everything still way off. That defeats the nice display and other features. It is completely worthless. I clicked on return and apparently it must be mailed back to china. Rather than doing that, it will take a detour into my garbage pail and I will begin looking for a decent cycling computer.

Satellites don’t connect anymore. This thing is a paperweight and I’m mad I ever bought it.Beyond the fact that my unit is no longer functional.-altitude is way off consistently-not being able to turn it on and off is terrible-no lap splits-could go into more but not worth it

be careful when updating firmware, make sure you use iphone to update the firmware. Do not use Android, this may cause the Firware update fail and it will not start. To fix this, simply update it again using iphone and it will work again.
