perfect working
This is good for only 1 device! 2 or more devices cannot be automatically connected, you will need to configure and search for bluetooth again each time, spending 2 minutes on it. It is not comfortable! I went out with a telephone into the courtyard, came into the house and spend 2 minutes on the connection again. A family of 3-4 people each has a device with music (phone) and each time connect the bluetooth with the device, every time! This is very annoying. The seller replied that you need to use 1 device.
