Summary: This replacement strap is identical to the one that originally came with my 405. When I first tried to install the strap I had some difficulty getting the pins to lock into place. Then I watched a YouTube video that Garmin had made. Once I saw the proper way to slide the pins into place I had the strap installed in about a minute.
Summary: There are several reviews that talk about the touch sensitivity of the bezel when running and sweating. I have had no problems. Before I start running I set it to the GPS mode and then lock the bezel by pushing the right 2 buttons at the same time. If I need to switch off that screen, then just unlock it and change. It's that easy. I used it for running and when I was traveling about in Afghanistan. No issues! I also use it as my cycling monitor for roadbiking.
