Actually no. I'm not that quick to judge the replacements.
I've given it about a week for the OS to settle down with all the new apps I've thrown at it with in the few first hours of getting it.
Now no problems.
I have all the apps I did on previous Passports and not a single hiccup.
The touch screen and audio feed back have been working flawless.
So leads me to believe that the previous replacements were hardware related issues.
