Review on Spigen Flex Strap Cell Phone Grip - Rose Gold: The Ultimate Universal Smartphone Holder for All Devices by Justin Munajj

I've read a lot of reviews complaining about bad grip. So I did exactly what it says on the box, cleaned it with the cloth that came with it, let it dry and put it on my case overnight and it works like a champ. Super thin, not bulky at all and feels super secure when holding the phone. And one more note: It's in a battery-backed case, so it doesn't light up at all. And it works amazing.
