UGREEN5.4 Bluetooth Car Adapter, [Noise Cancellation] Aux Bluetooth Receiver for Car, 3.5mm Wireless Audio Receiver for Music/Hands-Free Call/Home Stereo/Wired Speaker, 20H Battery Life

Works great, reliable, good sound quality, phone calls work great, bought another one for another vehicle, would buy again.

Easy to connect, works great, excellent battery life, and great buttons. Bad power button placement. Device turns on automatically if plugged in to power which could get annoying.

Functions as advertised. My only complaint is the annoying pairing voice instead of a beep sound like other bluetooth receivers. No audio quality issues and overall a decent product for the money. Body is made of plastic made to look like metal. Comes with a manual, charger, two way 3.5mm aux and some more documents.

I have a 2007 e350 and it works flawlessly on it. The sound quality is the same as if I was playing through aux, theres no delay, battery lasts a long time and it charges quick. The only thing I dont like is that it flashes when playing music, its a little distracting. Other than that its perfect

This has worked well as a Bluetooth adapter for my 2013 Kawasaki Vulcan Voyager. I’m able to stream my music from my phone to the unit thigh my speakers. I keep it locked in my motorcycle glove box.

This device has no security at all. Anyone driving or walking by can connect any time. It stays in pairing open mode permanently. Anyone can connect to the microphone in your car and listen while you are driving. Or, they could play something loud and obnoxious.The voice prompts when pairing, disconnecting, powering on, and pretty much doing anything, are loud and obnoxious. There is no way to change or disable this behavior.The bright LEDs blink and flash all the time for no reason except to be a distraction. You can't disable it.Beware of the large number of reviews which mention that the device won't work when cold. I didn't have that problem, but I plan on returning the device before that happens. I wish I had seen those reviews before I bought it.It doesn't have any kind of auto-on/off feature. It just stays on all the time, even if nothing is connected to the output port. You would have to manually turn it on and off.If you do turn the device off by holding the power button, it doesn't shut off right away. It stays on for another 2-seconds while it plays the obnoxious "power off" voice prompt. This is confusing if you don't actually have anything plugged into the output port, because it looks like the device isn't turning off.No play/pause button.Overall, this device is more expensive than almost every other adapter on the market but is no better, or is worse.

THE GOODUnit connects very quickly to both my phones and sound quality I hear is good. Unit turns on and connects automatically when power is applied upon turning on vehicle. Unit switches between playing media on personal phone to taking calls from work phone and back to playing media from personal phone seamlessly.THE NOT SO GOODMicrophone quality is middling; people with whom I speak complain it's difficult to understand me when I call using this unit.THE UGLYUnit will not connect when the temperature is below about 30°F regardless of the battery level. The unit does turn on, however. Warming the unit up in my hands for a few minutes resolves the problem. Emails to manufacturer were responded to promptly but no fix was offered (apart from a refund). Unit was returned.THE RUBIf you live in a non-freezing environment and you plan on mostly using this device to listen to media and only occasionally take calls then I recommend it for you. If you live somewhere where it's often freezing and/or you wish to make a lot of phone calls then look elsewhere.

Great for truckers, very good quality. Paid easy and connects easy
