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

I was looking for a good controller/phone clip and was hesitant to order one for my Steam controller after reading some of the reviews. but still took the risk. I'm glad I did. Perfect if you use it wirelessly like me. And it is adjustable according to the angle of the controller/screen. The rear bumper is still there. Very sure. does not move once attached to the controller until you release the lock.
