Review on SteelSeries SmartGrip Mobile Phone Holder - Compatible with Stratus Duo, Stratus XL, Nimbus - Suitable for Phones ranging from 4" to 6.5 by Jim Bijelic

I agree with everyone else. When you use the holder, it covers all your buttons on the top of the Steelseries controller. Note: This is not a third party, it is Steelseries. So how could they not prepare for it? Pros: - The screws at the base of the phone part can be tightened, allowing you to use it in non-vertical positions. but don't play lying down. It's only reasonable that the holder won't hold your phone if you're gaming while lying on the bed with your phone across your face. The holder covers all buttons on the top of the controller, including power. Therefore, to turn off the controller, you need to disable the controller. A huge minus - Could have been folded flatter. It won't fit in a controller hard case when mounted on a controller just because it doesn't fold AT ALL. Sure, Steel Series doesn't make cases, but that's no excuse for the phone holder part sticking out like a sore thumb when you fold it.
