anybody got one/use one.
Looking to pair it with an SRM PC7 monitor on my training bike.
Any advise welcome.

I bought one at the weekend and fitted it last night. I've paired it with a Garmin 800, and it appears to work fine. Mine came with remarkably few instructions, but fitting is fairly obvious from the images on the box. It is not as elegant as the Garmin sensor on my other bike, the spoke mounted magnet is particularly "clompy". There is a small button which turns on a little green light, no idea what that means, battary check perhaps? Still for €19 I'm pleased with it.

It's ANT+ so should work fine. I have a couple of these an they're generally OK if a little inelegant in design. I've had to take back one that packed in after a week or so, but the others have been fine though all weathers. One advantage over the Garmin sensor is that it's easy to remove and replace on the bike as it doesn't require cable ties, and they can be easier to position on bikes with oddly shaped chain stays. The cadence magnet is just a powerful neodymium disc so needs a steel pedal spindle to mount on.

Had one on my bike for 1 year with no issues, used with the decathlon computer it came with and later with a garmin edge 500.

I got one but couldn't get it to pair with my Edge 500, reading about it seemed that others had the same issue. Decathlon had a great returns policy on their own brand stuff though and I took it back about a year later for a refund.
