Summary: I first tried using it at Magmolia Greens in Leland, NC and it could not home in on the course I was playing. Magnolia Greens has (3) 9 holes courses, and the display showed 2 of the courses at the same time, and I could not get it to home in on the course I was playing. It never worked as advertised, and it was a total bust at this course. I had others in my foursome try to get it to work, we had the manual so it wasn't brain damage on my part.
Summary: Good for what it advertises. I would advise getting the s2 so you can get more information than just the distances. I like the band and the ease of seeing the distances, but would like to not have to charge it so often and to be able to use it as a watch also. I would have given a 3.5 if they had it. It's okay to I like it is where I would have rated this.
