I bought this bracket because different quantities smartphone can be attached with it. And that, I must say, very firmly! Through the two arms left and right with the foam in between, each known to me Smarphone can be properly clamped firmly. The holder itself can be rotated and tilted in all directions, so that it can actually be mounted anywhere. The screws on the axles can tighten up on the desired positioning with few small revolutions, so then actually wobbles nothing more. I attach the bracket always on the disk and then use my Iphone during the ride as Navi. Bracket fits securely even on longer rides on the disc.
Conclusion: + Robust housing + Friendly but still very solid fit + Different sizes can be clamped Rotatable + device in all directions
