Unpacking, and no smell; Surprisingly, I was expecting a rather strong smell after reading other users, but then nothing. The cover looks very small, I had never had a laptop 13 ", and frankly, a moment I was afraid it does not fit in, but no worries.
At the bottom of the base, an elastic strap and Velcro to hold the camera at the bottom of the case. It is not in any case excessively tight because, as I stated, the strap is elastic, so easy to scratch the computer without overwriting. It is quite well maintained.
The outer material is rigid, well enough to avoid scratches. Be careful, it will probably avoid not denting the macbook if an object were to strongly type the case. However, it seems to me excellent protection.
The inside is soft and molded to generate "channels" flow of hot air, theoretically allowing to use without overheating; I remain skeptical about the use of a laptop encased in a cover. This will go for some quick web, but it is not ideal in my opinion for long usage ...
All is well made, the seams are smooth and well finished, quality finish looks at the rendezvous.
In any case, a practical product, very cheap, good brand and well designed that I highly recommend!
