The product itself is optically not bad, of course, it helps a little bit to the thickness of the laptop in (for me it has not fit in my bag) and by the change in weight of the screen is no longer as stable and works sometimes very slightly backwards. But that is all in all not so bad and falls rarely interfere with.
The shell itself is fine, the plastic does not look cheap, only the feet are made of a foam material and look cheaper, but that does not really stand out for disturbing the pleasant to the touch surface of the remaining shell.
Respect. Cooling I had no problems.
The really bad point of the product are the projections with which the shell is clipped onto the laptop. Already at the first clipped a nose broke off a little, a few weeks later an entire nose and after about 4 months now broken even on the opposite side of the leaf ends noses use, whereby the lower part actually hardly stops at the laptop. The envelope was cheap and what they look and feel is very good terms, but I can throw away the envelope now is I honestly too early.
The on and off to make the envelope was with me no problem and has not led to cancel the nose, breaking it incomprehensible white easily for no apparent reason from.
