Pros:
- Good build quality

After 3 days of severe usage and using all operation must say that this is one of the must have gadget for your car. This is by far one of the best in calls when it comes to transmitng music or calls via car speaker. Though it is a car charger but believe me charging becomes 2ndary.

Kiraak product hai. Expected it to be a bit sturdier but works like a charm so no complaints. That bass booster button is a real thing. Aisa bass maarta…… poora seat hiljaara

Good working as expected. Just one issue is that it uses FM to transmit signal to car stereo and anyone nearby can tune into your frequency and listen to your calls or songs but the person needs to be very close to the car. Apart from this it is a fantastic product if you want to listen music or have calls without the hassle of any wires. Build quality and looks are excellent shows battery voltage when it starts. Go for it value for money product.

Works efficiently, quick charge works good but a little doubtful on the stereo sound. I feel it is mono audio. Call quality is really appreciable, no problem with the mic.

What an amazing product
1. Quick connectivity and clear sound with all beats and bass
2 Bluetooth calling is also clear and without distoration.
Overall a lovely product to add to the car if you don't have a bluetooth function in music system.

Call quality is poor...

Excellent product..buy it..worth for money

First ,very doubts to purchase by seeing some of the rating but after 2 week of usage I completely satisfied with the product.set it with any frequency instead of FM.it will work superbly.excellent just go for it

Nice Product
