Review on 📱 Newppon Sports Cellphone Arm Bands: Key Pocket Holder & 360° Rotatable for iPhone & Android – Perfect for Outdoor Fitness & Gym Gear by Adam Martinez

This headband exceeded my expectations. I needed something to hold my Galaxy S 9+ securely in the Lifepoof case and this did the job extremely well. The phone seems to bounce a bit when running, but that's because the grip is made out of a rubber band-like material. Still, my phone went nowhere. The rotation feature is very handy when I want to check my progress while running. The rotating part is tight and does not slip when running. 10/10 recommend.
