Fast, next-day delivery. Quick to set up & link to phone. Clear sound & lots of user-friendly buttons. I really needed this as my old 1 was on it's way out & I use mine every day. It came with enough charge to use instantly & was fast & easy to charge last night. It charges off the same connection as a general phone charger, which is helpful if it needs charging in the car. It's comfortable to wear & easy to use. Lets just hope it can go the distance!!
