I have used only the holder 5x, am so far very satisfied. I've read that it broke quickly in some buyers, with me for not luck. In road traffic, the mobile phone (iPhone 5s) keeps properly. Would I order stairs / drive across country, I do not know. But can try any myself, on the website at any rate advertised. By the way there is with the holder also for a coupon code which can be redeemed at a Navi app.
