Review on 📱 Universal Fit Bluetooth Rear View Mirror with 4.3" Auto Adjusting Brightness LCD - Master Tailgaters, Hands Free Calling with Built-in Speaker & Microphone by Eddie Fowler

Mirror monitor and Bluetooth both work well. Both my Android and iPhone connect quickly with no issues. The speaker was louder and clearer than I expected. However, I had a problem with the microphone. It needs to be kept very close (2-3 inches apart). Otherwise the sound will be weak and static. I contacted the seller and he sent me a new microphone. The replacement works better, but still not as well as we would like. I replaced it with the microphone built into the iPhone headphones and the sound is much cleaner. I suppose I could improve this by hooking up a karaoke mic to it. That would probably make it perfect, but no, I'll settle for the iPhone mic and leave that to someone else braver and braver to try.
