CRUST CS30 Car Bluetooth Device [Upgraded BT v5.3] with Call Receiver, FM Transmitter for Music System & Dual USB + Type C Charger; 7 Colour LED Lights; 6 EQ Presets; USB MP3 Support; Voice Assistant

Easy to setup and working as expected. Fast charging, USB music, all other controls are functioning well. I use an old model Nissan Micra which had only CD, FM & Aux inputs. After the CD player started giving troubles I was using Aux input for sometime which had its own inconveniences. Also my car did not had USB port so no charging option for mobiles. Then, searched and bhought this Crust30 just to enable wireless via bluetooth & Car's FM. USB Music & Fast charging are really useful to my car. Likes: Simple and yet good functioning. Music & Call quality is good. Turn off the car and restart it, the phone automatically connected and music starts playing from where it stopped. I use samsung music app. To be Improved: Wish this had an AUX output option also. As there is a very very minute difference in the music audio quality when compared to connecting the phone directly with Car's Aux and playing through Bluetooth FM. When in full volume a very low noise is coming. But be assured both issues are very very minute and merely noticeable. If you have an old model car just with FM and want to play music wireless then just go for it. This is my first product in this kind and it fulfilled my needs and I am happy. Many buyers mentioned about security/privacy that when other cars or FMs tunes to the same frequency as we set the other person also can listen to the music. But it is not an issue for me.

Nice product you get sound quality of fm radio and calling on this instrument was a good experience only thing you will have to increase your volume of car tape but it's ok overall wonderful product which provides handsfree operations

Amazing Product Easy Connectivity Build Quality Fits Correctly Calls Quality and Mic Quality is Excellent Sustainability Functions Good Worth for Money

I have tested the product today after delivery, it works good ,the sound quality and usb charging port works fine. Satisfied with the product.

Works like a charm, expect the body is not robust and breaks very quickly. Bought it thrice already cz I like everything about it but it breaks so soon that now I'm looking for a different option. The company should really bump up their product quality, it is BAD at the moment.

Really a good device for old cars, it's automatically switched on and works fine,connecting to car audio via radio frequency and connecting to phone via bluetooth is superb ,audio songs and voice call works well ,once again a must buy device for old cars which doesn't support pendrive ,bluetooth, today received and used it works well ,will post further comment after a week ,

Good device,easy setup, working fine

This is a very light-weight device that does a lot of things. A charger with two regular USB ports and one USB Type-C. It cleverly uses FM Radio frequencies for the output, pairs with your mobile through Bluetooth and has an inbuilt mic that picks up your voice which allowing hands-free. It looks pretty and has nice lighting as well. All in all, a very easy-to-use device. The only downside that I thought was the slightly low volume level (but it's not too low either and can be addressed through the volume control on the car stereo.
