Review on 🔥 HD Virtual Reality Headset - VR Headset 3D Glasses Goggles for Android & iOS Phones, Eye Protection, Comfortable Fit, Adjustable Distance, Compatible with 4.7-6.53 inch Smartphones by Brandon Mcvey

Works well! I use this to fly an FPV drone. Suitable for my rather large cell phone. Samsung Galaxy A21. Works seamlessly with the sjrc f11 drone. Take your time focusing it, it's blurry until you find the right position, but with a small tweak to the knobs at the top it's very sharp, as intended. An amazing glasses case that can be easily colored and customized with LED lights or whatever else you can add.
