Review: Best product - Best quality, but high price
Review: I received this device free to review for Sonru as a frequent customer. I still wanted to do an honest review so I used the device for a month to get a better picture of the build quality. Charger options: I used the device to charge an iPad, an iPhone, and an Android phone. Rapid charging was available thru 3 of the 4 ports. (The blue colored USB-A port is meant to have a thumb drive inserted to play music. It still charges, just not rapidly). When my wife and I were together we had two phones and iPad plugged in and all worked fine, but usually it was just 1 or 2 devices. The device charges as fast as plugged into the wall. 5-stars for the charging features! Hands-free device: Plug the device into the power (lighter) outlet, and press the button on the face. Open your phone's Bluetooth settings and pair to the device. You conmected your phone to the device. Now to connect the device to your vehicle. Find an FM frequency on your radio that is not being used commercially. Again press and hold the button until the FM radio frequency flashes. Turn the button to match the frequency on your FM radio. NOW, what happens on your phone will be transmitted thru your radio speakers! There is a Bass button on the side, which helps with the music playing. The other side button changes the light colors, and turns it off should you not want them on. Remember you can turn up the transmitted volume with the button on the front during a call or while the phone is playing. Need more volume still. Turn up the dial on your radio for even more. It plays very loud for me! The microphone on the device picks up just fine for most calls. If you play a youtube video, the sound comes out of your radio speakers. There is a lag time of about 1/2 second, if you are watching (not for the driver), but for podcasts, and music it is unnoticed. Sound quality during calls were extremely good within cellular limits. The improved Bluetooth connectivity really helps. I also know that sometimes changing the FM frequency can help also. When cellular signal was strong, so was the sound. The built-in microphone sounds as good as the built in microphone on our Hondas' hands-free links. As a hands-free device: 5-stars, after set-up. The instructions given in the owners manual are clear, but there are videos just above the reviews which easily show how to connect and use. OVERALL: A great device and a bargain. The charging features alone are worth the price, but the hands-free options seal the deal. So far the device has held up well, in colder weather. Thinking of more devices for our other car and as gifts for our kids! Highly recommended!

*by B***O on 2 December 2023*

Bought this in conjuction with the Miracase vent mount phone holder and the functionality of both together make my older vehicle as easy to use bluetooth as a built in new car integration. Plugged in securely to my power recepticle on my old Volvo's console and works very well. Phone functionality is excellent and bluetooth with music is clear and works flawlessly. The bass boost button on the side actually suprised me with its utility. When turned on, it enhances music but when I want it less intrusive and dialog to be clear in phone use, it is easy and effective. The hookup is as easy as finding any open frequency on your radio and setting a preset. Almost zero interference or crossover noise. The microphone works well for voice conversations, no complaints from listeners. Looks nice also.
