I've been having unjustifiable heart rate spikes with my Coros Nomad on my runs during low effort segments. The spikes are in 30 to 40 bpm over my actual normal heart rate which aren't small at all. I read and tried all of their suggestions for this issue before contacting customer service with no success. I contacted customer service and told them about my issues.
After several emails back and forth they ask me to repeat their troubleshooting suggestions already listed online. I entertained them and repeated them with no success. Then they asked me to have someone else wear the watch which makes no sense because even if it happens work in that moment I don't have any previous data on them to know if it's working correctly. They also suggested that I buy a strap style monitor which is the dumbest logic. Why would I buy another one of your products if the first one isn't working correctly?
So what I did was borrowed my girlfriends apple watch and wore it on my opposite wrist during a run. During the first downhill easier part of my run my Nomad was showing my heart rate was in the mid 170s while the apple watch said I was in the mid 130s(which based on effort and feeling was the correct reading). I provided them with screenshot proof that the watch was the issue.
They then asked me to send the files from some runs that I had issues on which I did. They are now saying they think the watch "wasn't snug enough" and now they want more data on another run. After 15 back and forth emails it's obvious they are giving me the run around because they continue to put the blame back at me.
The time I've spent communicating and troubleshooting this watch I could have spent at work and bought 2 or 3 of these watches with the OT. They don't have a phone number so I have no way of communicating with another person. Is this normal from them? I'm thinking this will be my last Coros product. Ticket number Y5KXG2-R21J2
