Roidmi 3S Multi-Function Bluetooth Music Car Charger reviews

Great little device and highly surprised at its small form factor.

Place it into cigarette lighter receptacle, turn on your device's Bluetooth, connect and tune your car radio to FM 96.4. Can also download the Roidmi App to adjust the FM frequency between 8.75 – 100mhz and an option to reduce the background noise but its not as dramatic as people are reviewing.

Pros: Small footprint, works on all cars with an Cigarette lighter receptacle and FM radio reciever, plug and play, Android/iOS app for car voltage checking, reducing static and FM frequency adjustments, Charging ability and can change LED color inside app or just turn it off completely. Cons: Receives calls through car radio but mic is used on the device, quality of music can deteriorate if the device is turned up too loud.

The charging is good, music quality is significantly worse than wired connection. Also, finding unused and clear fm frequency is somewhat challenging. Even if you find it, the quality of the music is not as good as wired connection. I would recommend buying this to charge the phone as the main use and not listening to music.

This small device is the best on the market. If you’re having troubles or music is not clear, you probably need to change the frequency you have set on the radio. My music is clear. Ofcourse near the city it is a little distorted but still very bearable, everywhere else it’s crystal clear. It’s simple and easy to use. The instructions not really clear. But just download the app, set your freq to a station with not much interference and boom you’ll be happy days!

Absolutely great device. The app is really handy and the connection is stable and effortless. I can set my phone to playing music and it'll connect and play straight away. The sound quality isn't the greatest as expected but it's good enough. Been using it for about 7 months now. Good purchase!

No English instructions works ok.

The device itself is really good and I really like the fact that it connects to my phone really easily, if I’m playing something it connects and keeps it playing so those are all great and it charges well, but the instructions were not in english, the QR code couldn't be scanned and the app couldn't be found in the app store (apple) searching on either Xiaomi or ROIDMI. The device is pretty much plug in, connect to bluetooth and away you go though. You only really need the app to change the frequency setting. The correct app name is MOJIETU.

App is a bit random. Asks for lots of permissions it shouldn't need, but you can still use it without giving permissions. The transmitter itself works well. Best we have bought to date.

Super easy to use – I got it working within minutes. Sounds quality is really good as long as you don't have the speakers blasting super loud. Device feels well made and solid. I'm very pleased with it, I would definitely recommend this to anyone who doesn't have an aux port in their car like myself. The app is really easy to use too!

Good sound quality

Fast charging with the 3.4 amps and no interference! simply download the amp set the station pair bluetooth and you're off!! buying a second unit for my second car!

This thing saved me $$$. Sound is crisp and clear coming through the radio no interference.

Instructions all look Chinese but relatively simple download app and pair on bluetooth.

Dual USB ports is also great will be perfect for the summer roadies and no need to worry about the aux cord.

Does exactly what it says and is very easy to use. Automatically connects to my phone when turn the car on which saves heaps of time. The app is very simple to use making it easy to change FM frequency. Would definitely recommend.

Perfect for cars with older stereo systems. Just plug into cigarette lighter and hook up to bluetooth. Easy!
