I moved away from Wahoo Tickr chest straps as they just stopped working this year and late last year. It is my opinion of owning two (more so for running), but there have been a lot of complaints about accuracy online. I can no longer rely on them personally but I have been more than happy with other Wahoo products. Also the chest straps can get loose and slip and cause chaffing in warm weather. Wrist based optical monitors have rarely worked for me being equally inaccurate or worse. So I bought the Verity Sense based on recommendations and I can say for sure, wearing this on my bicep, I have not seen one single blip. It is very accurate and dependable. If you just want to broadcast your HR to your wrist based device (overriding the built in sensor) or bike head unit, then I can't think of an alternative as good as this. If you want all the bells and whistles built into the device, maybe look elsewhere.Pros:Doesn't slip and stays put.Cannot feel it once fitted.Gets out of the way and just works.Optical HR sensor works 100% for me (6 months plus) with no wobbles.Easy to adjust arm strap and you can buy replacements.Easy to connect app so setup was a breeze.Good for HR training because of the accuracy.Very quick to charge.I don't really need to wash the strap after every use (if at all to be honest) because it doesn't really develop an odour (unlike my previous chest straps).Cons:Lack of add-on features that some other advanced devices promote.Polar app is not pretty and software could be improved.Would like to see battery status on opening the app without starting a session.Start recording on app did not like to run in the background on my mobile device when I tried it, but I might try again so I can't say for sure if it is a persistent problem.Quite pricey.
