ROCKBROS Bike Computer ANT+ Bluetooth Waterproof GPS/BDS/Galileo Position System

The computer works ok. However there is no option to turn on the backlight manually. It turns on automatically at 6 PM. This means it becomes completely useless between 5 PM and 6 PM in winter, when it is dark and most people commute back from work.

Decent design & study mount fix but reasonable functionality. Power meter broke first ride. Menu click through and setup not intuitive and rides don't appear to sync with Strava

The unit is great. However the instructions on how to set it up and use it are not very clear.

Very disappointed with my new bike computer from RockBros. The instruction manual is terrible. The menu system is not intuitive in any way. The buttons do not react consistently when pressed . The only positive is the speed reading is large and easy to read. To be honest I am almost ready to toss it in the bin.

after opening and checking out the computer , it does not do what I bought it for - I wanted to have heart rate and cadence displayd in large font so my visually impaired partner can use it . It cannot do that - it onle has speed - km/hr in large font and it cannot be changed . So I have asked for a refund /return

Delivery time was excellent. I found and still am finding the set up difficult - I had to go to Youtube, as the instruction pamphlet was useless. Using the computer I found the readouts visual size excellent. I am having trouble getting the HRM and distance to work simultaneously. Riding with a group I have found one other cyclist in the group is interfering with my readings i.e speed and HR. Still some homework to do for me to fine tune it at this stage.

Very happy with it and it's link to the XOSS app to store each rides workout data.
The Replay in 3D option is pretty impressive.
The battery life is very impressive. After 10 hours of riding with an elapsed time over 14 hours. The battery indicator is still showing 3 bars.

Have not received any package as yet.

Excellent bike computer that does not cost a fortune. Easy to use and rides can be viewed on XOSS app on phone.

Having used my M1 for a month now I have the following advice.
Do not buy this product.
My M1 no longer recognises any sensors. My rides usually have no data for about 80% of my rides.
Heart rate monitor and other sensors no longer picked up. Sometimes data is picked up and recorded for parts of rides. Unfortunately I appear to be dead for most of the time I’m riding as my heart rate is zero. Cadence, elevation and speed are so inaccurate Strava will not accept my uploaded rides.
Save your $ and buy something else.

The M1 instantly picked up all of my sensors, heart rate monitor, speed/cadence and power.
The provided user manual is simple but frustratingly difficult to change settings.
The M1 attaches to my Garmin brackets which is great for fuss free mounting to my assorted bikes.
Automatic download to Strava works well however there is no indication that a ride has successfully saved.

The M1 seems like a fantastic machine however mine has issues. Cant turn on and off the back light feature and also the auto pause is fixed in the on position making continual tracking impossible, very frustrating and the manual provided is poor.
The XOSS app is ok but will not work stand alone as it is designed to do. The other features of the app seem to work and the map overlay is a cool feature.
