Purchased the JayBird JF3MB to replace the Motorola S9-HD bluetooth, and am very, very happy with JayBird over the Motorola. I use the bluetooth primarily for cycling, and the JayBird is much more convenient to use and functions much better than the Motorola. In 6 months the Motorola was done, seemingly due to moisture damage which by design is unavoidable.
The product has been dependable, worked well in wet and dry conditions. I am very pleased. The devise is very well designed for use in athletics - such as cycling.
Better yet - i had terrific customer service with JayBird. ~ 6 months after purchasing, I had a problem with the microphone on the JayBird. JayBird customer support replaced the product - no questions asked - immediately, and I dealt with professional, polite, knowledgeable people, all located in the U.S.
I will buy another product from JayBird simply from my experience with customer service.
