question:
I'm not sure where to go wrong with this review. The first time I put it on my Nexus 7. It is too small, but the second time, it stretched out enough that you could tell its there. When you stretch the thing, it loses contact and stops working. Not worth trying again. Went back to Zagg, who also made an excellent product. This one just does a bad job. Save your money!
