I used this on my 1st gen Vivoactive watch and it was very good. I've ridden my road bike a total of over 200 miles with this mount and it hasn't slipped or been moved and my watch is securely attached to it. The only reason they have 4 stars is because I had to make holes for the zipper and then didn't use zippers at all. I tighten the watch on the mount as tight as I can and it works fine. I also left it untied so I could attach it to my mountain bike.
