it doesn't come with the longer cable you need. You must support a 10 inch tablet, the weight will stack the tablet on the controller. Even after tightening connections. Wrap duck/racing tape and use some wood or plastic as a wedge. If you let go of the controller to attach it to the strap, it may detach and your controller will fall to the ground. You need to connect the device to the controller. Somehow I use zip ties. Yes you will have to cut and re-attach each use if you want to store this in smaller carrying cases. Drill a hole on the edge of the device where you can see the device through the controller slots. You need a hole at the bottom of the slot to allow the device to fit snugly against the controller. If you have the ability to drill a slightly larger hole on the edge, you can use quick release pins from a racing supplier. Drilling on the edge is difficult with a press and clamps. The rest works fine.
