With this California law going into effect, I purchased a Bluetooth. Normally, I stick with Plantronics as they simply produce the best quality and sound. I opted to go with this Samsung. Samsung has relatively very good quality electronic devices, but this one is ......well...so-so at best.The BT fits fine and it's snug and light. But let's get to the real question; does the thing work? Yes and no.It works fine in a quiet environment.It has NO noise canceling, so it WILL pick up everything.You sound far away 4 out 5 times making a call.Functionality, it pairs well and it's a quality made product, but it's working capability is 50-50.I'll use this till it breaks or get's lost (in my case, it'll get lost).If you all have a few extra bucks and want the best of the best, then I recommend you pick up a higher end Plantronics or Jawbone bluetooth. Unless you're prone to lose things or break them, then go with the cheaper BT's.Hey - you get what you pay for.I'll pay for a Plantronics or Jawbone next time.
