used for 2 to 8 weeks The Ant+ sensor will not connect to the Tacx app which I wish to use with my Tacx Blue Motion turbo trainer. I have the Samsung Galaxy Note 3 which is Ant+ compatible.

used for 3 to 6 months Had two of these on separate bikes and both failed within months with water entering the battery compartment. The sealing of the unit is only good for dry or indoor use.

Response of the brand

Dear Sir,
Thank you for your feedback.  I'm sorry to read that the sensor has not withstood wet weather.
I will forward this to the product manager at b'Twin.
Regards,

used for 1 week or less Once a new cr2032 battery was fitted the test button gave a green light from the led. It then paired easily with my Garmin Fenix 2. Brilliant

Great price, for a good product - Magnet fell off.

used for 1 week or less Was really pleased with this unit, cheaper than Garmin GSC 10. Easy to connect and attach to bike, however during a 90 minute ride, the magnetic on the crank for the cadence fell off....

Seems to work for me

A bit ugly, no online documentation

used for 7 to 12 months I had no problems installing this or getting it to work with my Garmin Edge 500. I've probably done over 1000 miles with it now, in various weather conditions, and it's still working.
BUT - the documentation that came with it isn't great and I may have thrown that away. I've contacted Geonaute asking for some information on it, i.e.is the button on it a battery state indication? If so, does it show red instead of green when the batter is low? How long can I expect the battery to last overall (roughly) and how long have I got left when it starts to show the low state?
The response was a link to a (French!) quickstart document for their Count14 product which hardly mentions anything about the speed/cadence sensor!
While overall I'm pleased with my purchase, availability of proper online documentation (in English) for this needs improving.
