Hello Garmin team.
I love my Garmin Forerunner 610. I started using Garmin since December 2009, I had the Forerunner 405 and it was great, but the thing with that watch was that the wrist strap ripped off and I had to replace it twice.
Later in 2011 I bought the 610, and it happened too, the wrist strap broke and I solved the problem buying the Velcro strap, it's nice comfortable and it last longer. But today I write to you because I know you can use a better material to make the back of the watch in order to make it more durable, I am attaching a pic of my Garmin and it is very corroded because of my sweating I think.
I hope my comment is helpful for you to take action.
Have a great week.
Felipe Uribe :)
