"I love it. The Forerunner is the new I-Pod for runners."5.0 starson by anna_klein
Pros: You can go for a run on a whim and not worry about getting back home. The GPS takes you back to start. I had the NIke Plus application that hooks up to your I-POD - but the Forerunner 405 has better cal/HR/MPH etc.. and I can wear it with Asics:)
Cons: It takes a little getting used to. I recommend reading the manual and watching the demonstration video on www.garmin.com
Summary: For the novis runner or jogger - this is a great tool. For the hard core outdoor fitness enthusiast - the forerunnner 405 is a must buy.
