Quality disappointed

This is my first review on Amazon, but unfortunately no good!
I've been looking forward for some time on the Nexus 7 and even then a pre-order at the local MM.
Out of the box and on the disappointment: two steady red light pixels. Can happen sometimes
After a little while back bitching at MM I've been waiting and looking forward, that it also offers Amazon now directly.
So quickly ordered and delivered, but after turning back the disillusionment. Again a pixel error, this time a black dot. After a disappointing mail to Amazon, I got today now my third Nexus 7, it took out and ...
... And again it has pixel error (Black and White)
Therefore, I must say, in my view, that I will look for another tablet.
The quality of the Asus has delivered me up to this point is abysmal.
Of course, you could now come up with pixel errors guidelines, but as a customer I expect simply at a price of 269 euros a flawless product.
