Beware, this is absolutely perfect for a "super slim", but it will probably not if the computer is a little thicker. I think it will not be enough to overcome more than 16/17 mm thick thicker.
No comparison with other silicone case that I had initially bought for just less expensive: my computer fleet in, and as it was planned for the diagonal of 13.33, but it works for like 16/9 for the 4/3, it must float on one side. For 3 more, there's really no match.
The computer is well protected, it looks like a very clean record. Protected against the coup as theft, I think ... It does not shout to the four winds that it is a computer that is inside. I think even against shocks, it is well protected in the sense that both sides of the cover are "welded" one over the other (as we can see on the picture it is open, in the illustrations Ad). So if he 'fell' or faced something, it dampens because it is extremely well settled in his Pouche. This being ensconced protects far more than these covers when it floats.
In any case, should it fall, I'd rather it be when it is in there that when he is in a thick silicone case where it floats. However, normally it does not fall ... it is arranged to care.
I regret not being able to put a sixth star.
