I've searched a bit (not this entire thread) for a picture of the back of the perfect squeeze. I'm assuming that I'll need a Ram ball mount to work in my existing Ram system. Does it just attach directly to the back of the perfect squeeze? I've been on two rides this last month that my phone vibrated out of the Ram, and through a miracle my charging plug caught it. One at 80mph. I'm not losing a $1K phone over a $25 crappy Ram holder.
