Good - but seems to have durability issues

Great - it does exactly what it should

Durability...

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.

Not waterproof

Fails again and again

I have now returned three of these devices. The first one failed after a couple of months. The second one failed after a very heavy downpour and on this occasion when I replaced the battery (which I did each time before returning it to check I didn't have a duff battery) I noticed that the battery was covered in a gunky mess and clearly mud and rain had got into the unit. I ride a road bike so its not like I have been taking it through streams or muddy fields.
Third time lucky - nope. Failed again after a month and yet again in the battery compartment is evidence of water and gunk. I got caught in a ten minute downpour a day before it failed so can only put it down to that.
I have not opened any of the devices until they have failed so it is not a case of not re sealing it correctly.
On a positive note, Decathlon have been very good at replacing them but I guess you get what you pay for. This time I will be after a refund. Not fit for purpose.

Response of the brand

Dear Sir,
I'm sorry that you've had so many issues with this product.
I have contacted the product manager directly to resolve these issues as quickly as possible.
You are correct that in it's current format it certainly seems that it's not fit for purpose.
My apologies for this and I hope we can find a quick resolution to rectify the waterproofing.
Regards,
Peter Lazarus UK Market Manager DECATHLON

Pairs well to watch and cycling computer

First unit failed after 3 months

Unit stopped working after 3 months, tried changing battery but new batteries did not even make the battery check work! Ordered another as price is good. If it fails again, I will have to look elsewhere

Doesn't work

Used this item a few times and it kept on stopping working half way through a ride. Unfortunately as my garmin is connected to it, the garmin wouldn't start again because it thought i wasn't moving. Very annoying.

Response of the brand

Dear Sir,

I'm sorry to read that you've had issues with your ANT+ sensor.

You can pop down to your local Decathlon store for a replacement batter/unit if you wish, if you are not able to do so, send me your address and I can send you a new unit/battery.

If you would prefer a full refund, it would not be a problem either.

If we find that the unit was faulty, this will be fed back to the product manager automatically.

Regards,

Peter Lazarus UK Market Manager DECATHLON

Not worlking ANT+ compatible device

I am unable to make it work with Garmin 310XT. This product is not working as advertized. "Thisisant.com" says its compatible. I read in a forum post that units before 12/2012 doesn't not work with garmin. Is that the case?. My box says imported on May 2012. Can you please confirm this works with garmin 310XT.
