Nice if you can not see what you bought.

Admittedly, I do not have a long-term test, because I have only glued a film on my Tablet. This worked smoothly and virtually bubble-free. Almost without bubbles, because I do not live in a laboratory-like purity and clean room. The guide was, as usual of Savvies, good and helpful. I had to get the supposed happiness which half dozen films for the price of 2.58 euros on Amazon. But even if they have become a little more expensive, they are an inexpensive alternative to other, more cost then the same multiples. The tablet could be in any case operate in every corner of the display and see everything properly. Only the camera is also pasted over, because there is no stamped recess - which is at the Trekstor but perhaps just as well ;-)
Conclusion: I would buy again - but that will probably take, since I still have 5 in store!
