Review on 📸 Versatile Selfie Stick Tripod with Bluetooth Shutter: Extendable, Lightweight, and Compatible with iPhone 11/XR/X/8/8P/7/7P, Android Phone, Gopro, Webcam, and Camera by Troy Larson

The battery is already installed, so ready to use. Cone also with additional battery. Seems to be well made and sturdy. Folds securely with no loose parts so you don't lose the detachable remote control. I didn't use it as a selfie stick, just a tripod because I needed something to hang my phone for web meetings and it was a great find. *** Update for those asking how to change the battery. There are no instructions, but sticking a nail or coin under the slot on the side opens the remote and gives access to the battery.
