M6000 Button Mobile Phone 2.4 Inch Screen Large Speaker 2400mAh Dual Flashlight Camera FM Four Card 2G Feature Phone

Very disappointed! At first glance, it's very good, the flashlight is powerful, the battery is the same. BUT! When I started using it, the first shortcoming was the sound during the call that comes from the rear speaker, not from the top of the screen. For this reason, the interlocutor is poorly heard. And if I make the sound louder - the interlocutor is heard by everyone around, and that without turning on the loudspeaker. The second uncut - I am not heard when I call someone. I have to ring two or three times, and then I am heard. At the moment, I am waiting for the response of the customer support service for the refund of the money.
