It was very convenient because you can work with both hands while calling. I bought it five months ago as to whether the conversation is easy to hear and there is no problem but the power did not suddenly enter after charging. The cause is unknown.
Although it is the third purchase this time, since the price is reasonable and the style is good, I purchase it continuously. However, what I bought this time has very bad battery and I do not have a day. There are things you do not even have for half a day if you go back to it. Is it the initial malfunction? Is exchange possible?
