How long should a HRM last?

happy_jax

So...does anyone know how long a HRM should last?

I have loved my faithful Polar F11 sooo much for the last 5 and a half years and it has been amazing, but the past few weeks it's been dropping to "00" quite a lot so I've had to guess quite a lot of my workout burns. No amount of washes, battery changes and even a new chest strap has improved it...so I'm thinking it might be time for a change. (It has served me very well, I will just be sorry to say goodbye!) :laugh:

I'm looking at the Garmin Forerunner 110... but don't want to spend money un-necessarily....

If anyone can advise:
a) Suggestions for things to try and make my Polar work effectively once again...this would be the ideal!
b) Whether the Garmin Forerunner 110 is any good?

Thanks in advance for your help! :happy:
