Easy installation, connection and good voice quality

I use the speakerphone in a Opel Corsa D. The voice quality is excellent in my opinion, only in areas with poor network coverage, there was occasional dropouts - that exist but without a hands even with a phone call.

Vulnerability, and therefore, unfortunately, 1 star deduction: In some vehicles, the placement is certainly tricky if you do not want to lay the cable across the dashboard. I have stuck the microphone at knee level, to work properly, as it shows the driver's seat. However, the cable must remain open, if one does not open the dashboard, and the plug, if you use the instrument seriously, always connected to the cigarette lighter. It can be for this but at least a USB charging cable for your phone plugged so that the slot is not completely lost.

For the price certainly with the best solution!
