Review on Wireless Bluetooth shutter remote control; Bluetooth selfie button by Van Chayathon ᠌

It still connects 2 times out of 3. There are no sensible instructions for it, so I don’t even know how to replace the battery later. One recommendation to connect to a smartphone without failure: turn off the bluetooth on the smartphone (if it was turned on). Turn on the remote control and wait a minute (the indicator flashes quickly at first, then slows down, but it’s better to wait a minute), then turn on the bluetooth on your smartphone and connect the device. With the camera turned off, pressing the remote control button increases the volume on the smartphone. It cannot be called a disadvantage, but it must be taken into account.
