    Good and convenient

    Cannot wait to open when arrived. Easy to install in my car, hold the button and wait for 3 seconds, it connected to my phone and car radio. Finally, I can play music with car radios without using my Bluetooth Speaker. (Yeah, my car is old and cannot connect Bluetooth directly. ). The only problem I see so far is it has some light noise, like when tunning the radio there always some noise if not totally covered with good signal. Considering the price, I could say the product is fair. Not fancy but workable and could bring more joy while driving.

    Perfect for cars with no aux or Bluetooth

    I’ve had the product for a few days now. I love it. Sounds great, perfect size and super easy to set up. Shipped and arrived sooner. Remember to find a station that has no static.

    It's excellent, but there's a few caveats

    – Once configured and connected, the sound quality and ease of use are excellent. The device name isn’t obvious, but once connected the first time, it will continue to connect automatically when the car is on.
    – The device is built very well. It doesn’t feel cheap, and in fact, it has a decent weight to it. The materials feel premium.
    – Playing music from your phone through your car speakers on this thing is where it really shines. The connection is strong and the sound quality leaves very little to be desired.

    – Depending on the location of the outlets in your car, the microphone quality can go from good to terrible. We tried this out in my wife’s Toyota Yaris where the outlet is located under the stereo controls, about parallel with the driver’s thigh. This made the microphone sound a bit muffled when having a conversation.
    – The sound quality is entirely dependent on the placement of the outlets in your car. Before purchasing, make sure it’s in an open area somewhat close to your mouth, otherwise, it won’t work as intended.

    Despite the obvious drawbacks when it comes to microphone placement, this thing serves as an excellent way to play music through your car stereo. Once you find a radio station that’s broadcast-free, it’s as easy as setting it as a preset, starting music on your phone, and listening to your heart’s content. The sound quality is very good!

    It connects every time the car is turned on, that’s good.
    installation and set up was just difficult on this particular car with the cigarette lighter in a hard to reach area, so using the buttons to clear out the station was just a bit difficult, otherwise after that i don’t need to mess with it anymore.
    I’d buy other ones if it wasn’t so portable so i don’t need 10 of them for every car.
    price is good and it works as it should, not sure why others are having so much issues with them or giving this thing a low rating. you do you

    I’ve used a ton of these. This one has a very good sound quality. Also the low profile is nice because my kids always kick the ones that stick out.
