This blue tooth head set replaced another that worked fine, but came off too easily. This one also works fine, absolutely no problems linking it with any phone I have tried. The great thing is that I can be active and this one stays on. The other thing I like is that the indicator lights are on the inside where they can't be seen flashing by everyone around. Sound quality on both the ends of the conversation are acceptable. If I ever lose it, I will replace it with another just like it.
