I bought two of these and have been more than happy with them. The sound quality on the mic is better than the built-in mic (not in speakerphone mode) on my wife's phone. I have bought other kits like this before only to be disappointed in the low quality mics, but that is definitely not the case here. The kit was relatively easy to install, and includes long, high quality cables. The only downside about this unit is that it does not have a screen/display, but those cost more.
