Review on Enhance Smartphone Photography with eCostConnection Wireless Remote Control Shutter Buttons: Compatible with iPhone and Android Smartphones, Black, Round Design with Bonus Microfiber Cleaning Cloth by James Wiley

unreliable connection with the remote control, sometimes the connection was established immediately, sometimes the remote control had to be "found" several times. It has trouble connecting to multiple phones, for example it connects fine to mine but when my friend wants to use the remote control the Bluetooth doesn't connect to his phone. Even if the Bluetooth connection is disconnected from my phone. After several uses, the buttons on the remote broke and didn't press, rendering it unusable. In addition, the battery discharges very quickly. A battery powered device would be nice. If you intend to use this remote frequently, I would suggest using a different brand. If you only plan to use it a few times, you should be fine.
