Is there a Natural Life Expectancy for a HRM?

... Im actually a bit of a meany, LN, and didnt intend to get a new one. But you know what its like... you go onto Amazon, see the price of everything, do the "havent the prices come down" bit, then the "ooh, these are are a lot smaller than the 301", then the "oh, isnt that a nice colour", then the "gosh, look what you get for just £20 more" and before I know it, Im looking at a 910.....

Fortunately, I have come away from the 910, but the new ones are so nice....

I've been using a series of Garmin HRMs over the years since 2005. I've had a couple of straps where the chest strap just stopped sending reliable signals after a couple of years' use, despite scrubbing it and changing the battery. I gave up and bought a new strap. the newer ones are more comfortable anyway. That fixed the problem. Who's to say I couldn't have fixed them if I had persevered, but I prefer to use a little money rather than mess around for hours and keep having signal problems.

The watches themselves last longer and I'm still waiting for the 310XT to have a problem so I can justify a 910

Sometimes the watch prices vary because a chest strap is not included.

Thanks for that, Steve. I have a feeling it may be the strap, but will have to pay £40 for the privileg of finding out.. OK if it works, but not if it doesnt...

Think Im like you...... want a new one, but cannot fully justify it....

Checked Amazon price, and yes, strap was incl.
