A quick comment on the tools suggestion. Three times now I have gone to a hardware store and bought something that was suggested by someone that would work for me. After the 3rd failure I promised myself I would not do that a fourth time.
For no reason this morning I took the (new) battery out of the Tickr (maybe to again experience how easy that is) and I did want to see if I could see any sign of water intrusion (I did not). On putting the battery back in just for grins, the Wahoo came to life (at least those little blue and red lights started to flash).
Two hours later I went for a ride - Wahoo Tickr was absolutely dead (less than a year old, BTW). And after the ride a battery change did not help.
I am now trying to decide if I care - I have a power meter so HR is more just a curiosity thing. And I am tired of buying stuff just to satisfy my curiosity (3 tools/toolsets and 4 HRM straps).
