Looking for a bike mount on my Motorbike topic

I have been looking for a Galaxy S4 bike mount for my motorbike for weeks, but most products on amazon have too small slots to fit in the motobicycle, I found this on internet and it seems to work,
Double-Lock Style Universal Bike Bicycle Mount for Smart Phones and GPS

Anyone has the same issue? It would be awesome if I can learn some advice before the purchase.
