Love this thing. The strong smooth hinge is the key, as it magically keeps the kickstand/handle in whatever position you want to hold the phone. You can use the stand as a handle running perpendicular to the phone and it holds its angle easily. This means you can change your fingers and hand position a lot and this handle changes with you! The strap adjustment can allow for less or more fingers, so you can use the strap for loose support or fit it tightly so you don't even have to use finger strength in some positions.
And it's a kickstand! So stable. The hinge they developed here is magic. The magnet ring holds on strong, but also spins easily to change the kickstand angle or pull the whole thing off for charging.
Ergonomic and adjustable.
