Summary: I purchased the 405 because of the GPS Receiver so that I could track my mileage. Apparently there is a great deal of work to be done to properly set up the forerunner and I have not gotten that done. The acquiring of satellites seems to take forever and is perhaps my greatest disappointment with the Forerunner.
Summary: When my strap broke, I wrote to Garmin whose advice was to buy a new one and they would give me an $80 trade in for the old one. They did not mention this much cheaper option. There has been some debate over the relative difficulties of fitting these and I would suggest that those expressing the sentiment that it easy are a little off the mark or happen to be extremely good with their hands and fiddly things.
Good replacement part, but installation is anything but easy.

Summary: Garmin bands are known for breaking, but at least this watch has a band that is replaceable. Nice replacement part but even with the tool provided it is not easy to replace. Without the special tool it would be impossible in my estimation. Take your time, follow the instructions and you should be okay. Just don't expect it to be a quick change out.
