Great product and my Apple TV Steel series Nimbus controllers fit perfectly. I actually modified the holders and installed them with screws and the 3m clear sticker they came with just in case my son takes them off, they are more secure now. Instructions how I did it: First make a mark in the middle where the screw will be and make sure there is room for the screwdriver you will be using. Don't make the hole too high, make it closer to the ground, about 1/4 inch from the bottom edge. There is also a photo for you to see. I then took a screw of the same size you will be using to attach it, it got very hot and tried to penetrate the plastic mounts, but the mount is strong plastic and didn't go through. I then took a metal screw and lightly drilled through it. The hole I marked with a very hot screw first helped make it easier to drill as the screw didn't slip, it came out fine. If you use my method. Much luck! The company should get them to mount it with screws and also for people like me who want it extra secure. You should pay me for this idea. lol :)
