Bringrr's were delivered today. No problem pairing it with a VZW iPhone 4s. I won't have time to do much with it until the weekend, but here are a few initial comments...
1. Buzzer seems loud enough. I can hear it over the radio at normal levels.
2. Light indicators are not very bright. On a sunny day, it might be hard to see the "light rings", especially if the Bringrr is a little of sight, like with my car. If I can't figure out a way to relocate everything behind the dash and have an external light indicator, I will probably need to get an "extension" for the lighter socket so I can mount the Bringrr in a closer, more visible location.
3. It finds the iPhone within a few seconds of starting the car.
4. I may have something set up incorrectly, but...unless I actually have my iPhone on the Bluetooth screen, Bringrr doesn't detect it. For example, the Bringrr doesn't detect my iPhone if my iPhone is on my "home" screen. I will probably email Bringrr support to see if I've done something wrong, or if it is working as designed. If it's working as designed, this will be a major problem for me.
