Not bad at all
I bought 4 tough cases for me, and my husband. So far we have not started to throw our phones around on purpose to test how tough the case really is, but the times our phones have fallen they are in one piece. No shattered screens, or loose parts inside the phone making noise when shaking the phone.
The printing quality is truly delightful. And it is true, no scratches appear. Mine has been together with sharp metal parts, and fallen on floor that had sand particles all over it. No scratches. true.
