[Bamboo] 7.9 "Acer Iconia A1-810 A1 Smart Cover Case PU Leather Case With Support Functions For 7.9" Acer Iconia A1-810 A1 + Pen, Violet (Electronics) 4
I offered this cover with the Acer tablet to a novice, and she is very happy. I myself have used it and I find the cover rather strong and easily manageable. The grip is nice and perfectly hold the tablet when it is placed in landscape through the cover.
The value for money is more than correct. I recommend it.
