My Garmin Dual HRM lasted 2 years on its little CR2032 battery; it finally died on me a few weeks ago.
No complaints with it at all, it’s been great, and has always connected to my watch, Edge, and Zwift without fuss ever (well, until the battery died, more on that in a second).
If I had to produce a complaint; it’s that Garmin Connect said the battery was “OK” on literally every ride, even including the one where it wouldn’t connect / died.
Which, there wasn’t much warning. I had just noticed it didn’t want to connect to Zwift one evening. It did eventually, but took longer than normal which was the first sign… beyond that, it just dropped once in a while during a ride.
So a better warning that the battery was going, would’ve been nice…
That said; something like 1200-2000 hours on a CR2032 is insanely impressive.
Downside of course to a lot of HRMs, minus those rechargeable ones folks are talking about; is the need for those watch / glasses sized tools which most folks don’t have (and for some reason aren’t included).
But most folks I’ve heard have always said either get the Garmin Dual or one of the Polar straps.
I’ve heard most complaints indeed with the Wahoo Tickr just going out probably more than any other device which is unfortunate to hear.
Only thing I’d be cautious about with those arm bands is they’re LED/light based much like watches, which can sometimes get pretty inaccurate when you start to get sweaty (I imagine this does greatly matter person to person though). I know my Garmin Fenix gets quite useless after about 10 minutes, which is when I eventually got my Dual HRM strap.
HR values wouldn’t necessarily drift, but they were slow to respond / never that accurate.
Whatever you end up with, particularly a chest strap; definitely just make sure you wash it UNDER A FAUCET, and lightly scrub it.
I think most folks manage to kill their straps by tossing them in the clothes wash, or just being overly aggressive when cleaning them, which leads to premature failure.
As far as smell goes; Lysol has a disinfectant / anti bacterial spray, and clothes wash soap… 10/10 recommend. I’ve been using it since early summer when someone told me about the stuff, and have been using it on all my kit since; all the lingering smells are gone; definitely worth using on HR strap as well; as they can get… quite smelly.
