At first I found it very nice for a screen as 8 inches is better designed than the 8 inches of my Galaxy Tab 3
Indeed it is square while the Galaxy is more rectangular, here are the steps:
Gigaset: 16 cm x 12 cm
Galaxy Tab 3: 17 cm x 11 cm
It's played at little things, but one centimeter more in width it's very nice. (Ok you lose one in length, but the comfort is there)
As against the speed is not what it has better of in this area where it is better not to compare with another well-known brand like Samsung because the difference is noticeable.
Image quality, same no comparison like that no regrets.
But mostly I blame shoddy printing, on materials.
She even has a side that does not clips (clips of the cover are probably broken, and I do not disassembled in fear of breaking the rest.)
So to put it simply very good tablet, it is not of great quality but working fine, with a comfortable screen and not too much surplus.
However, I recommend it.
