The heart rate detectors appear to keep failing on these straps - I've bought 4 straps so far. 2 went in the bin and these were bought to replace them.
The original strap which came with the device (bought around February 2014) worked fine until this week. I bought replacement straps to be used when needed, but both straps failed on first use. Now out of returns time so I'm going to have to buy new ones again!
When the heart rate detectors fail I get a 0 for my pulse rate. It sometimes re-starts, more often doesn't re-start.
It's a lot of money to buy and then find out it's faulty.
Apart from this problem, the rest of the device works very well
