Functions good, build quality not so good

Has all the functions you need. Clear to read

needs very precise adjustment and falls to pieces

Had this for a month now and had a difficult job to get the adjustment just right. On bumpy roads the vibrations either shifted the magnet on the spokes or else moved the reader unit enough that it would not read the magnet. And then after about 30 miles the computer flew off the handlebars on a bumpy piece of tarmac. I managed to collect all the bits and when I got home I discovered that the two little screws that go into the back of the mount had worked themselves out. I screwed them back in tightly and it seems to be ok again. However in realigning the spoke magnet the plastic screw sheared so now the whole thing is no use. Is it possible to buy the spoke magnet separately?

Response of the brand

Dear sir,
Because the bracket did not hold the computer on correctly, please return it to store and we will give you a whole new unit.  This way you won't have to pay for a new magnet screw.
If you bought it in store, just take it back (even if you no longer have your receipt) and if you bought it online, just click on this link to arrange the return with our customer advisors:
I apologise for the issued encountered.  I have forwarded your comments onto our product manager at b'Twin.

Easy to Set Up

The cradle/mount is no good

Bought this product under a week ago. Easy to set up and get on the bike.
1st outing on the road - hit a bump as we road cyclists often do and the computer flew out of the cradle and got run over by a car.
Extremely disappointed ss Decathlon products are usually excellent and always robust.
Not convinced that this should have happened at all never mind on the first outing.

Response of the brand

Dear Sir,
I'm sorry to read that the bike computer fell off the bracket.  I have fed back issues with the bracket to b'Twin and it currently being redesigned by our engineers to avoid issues in the future.
Please don't hesitate to return it to us a for a refund/exchange.  It really would not be a problem.
