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.

Lost my magnet whilst out riding.

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.

Total rubbish

None

Good - but seems to have durability issues

Great - it does exactly what it should

Durability...

used for 7 to 12 months First up - it's half the price of the Garmin GSC-10 and it does the same job. It's easier to position and appears to be more durable than the Garmin piece but I have had two here in less than a year go bad - losing the ability to detect pedal cadence (swapping new for old and keeping exact same positioning it works again - so not a magnet position issue, battery changed in both cases and no improvement - so not battery life either).
That said - it lasted longer (for me) than the Garmin and it's half the price - *almost* a disposable item.
The instructions on the device are very light - but the basic is that it needs to be active to pair - activation happens when one or other of the sensors detects the magnet passing by - so spin the wheel or crank (or simply pass the magnet past one of the sensors to wake it)
Despite the negative of durability - I'll still replace these ones like-for-like.
