ULANZI O-LOCK020 Smartphone Grip Holder - 3104

O-Lock allows the phone case to rotate on the O-Lock mount. But the tiny detents in the O-Lock rotating ring are insufficient. In my testing, my phone gets tilted on the O-Lock mount often. Worse, if I add any extra lenses to the iPhone case, the slight extra weight causes the phone to tilt on the O-Mount.
Ulanzi also makes a heel grip for their O-Lock phone cases. The heel grip is much smaller and lighter. It offers most of the benefits of this handle grip and none of the drawbacks. It's a better choice.
The handle grip was interesting. I wanted to like it. I own it and I tell myself to keep it around... but I know I'll never use it again. It's clutter. The heel grip is the better solution, in my opinion.
