Now for the subjective disadvantages: The tablet looks really heavy with the shell than I thought, and when you hold it in your hand, then you have the feeling it was a lot thicker. But it is even thinner than the "naked" iPad 1 Case with itself.
The biggest drawback is the too small opening for headphones, because that does not fit nearly any plug in. I can devalue the correct envelope not because the original headphones that come with the tablet fit.
From me there is but a buy recommendation, because with a screen protector, it is then completely well protected.
