I have one, it’s an excellent product. I have about 1km of range with other units, it bluetoothes to my phone and is simple to use. I use the gps on my phone, music, and phone calls and it is smooth, passes gps directions over my music and lowers the music anytime you speak or anyone your paired with speaks. Completely changes a ride. I have the pactalk. If you load the app on your phone you can control everything from or use voice commands that actually work or the buttons on the side of it.
