My two year old Forerunner 50 with foot pod went wrong years ago, for £20 Garmin sent me a brand new replacement. When I upgraded to a 405 it went wrong after 2 1/2 years. Again, Garmin replaced with brand new for around twenty quid.
My 405 is still going two years later so that's roughly 10 years of Garmin at around £200 spent.
Their customer service was fast, efficient and extremely polite. I would never fail to recommend them.
