For housing:
For the board it fit like a glove. While there is no installation instructions, but in my opinion it does not need. The board fits tightly in the housing floor, but can also be taken without major problems out again. Furthermore, the processing makes a good impression.
All inputs and outputs or connections of the Raspberry Pi are also available with housing without using Einschrängungen (ka why one has complained about the "power socket"). Although the case is not clear, but the (very easy) milky plastic is in my view no gripe is - especially since the (incorrect) original image of the article is not clear. It fulfills the requirement "clear / transparent".
The rubber feet fit for purpose, are slightly recessed deducted from the rest of the housing, so that they should remain in place. The housing slips on smooth surfaces only slightly.
But now the criticism of the case, which is why there has been a star deduction:
Although it has as described holes in the ground. But the holes that would, according to the product description should be in the cover missing. Thus, the ventilation is described ad placed absurdum. So if you want to operate its Pi at the stroke limits, need to look at another case would prefer. Because the distance between the holes for the ground on which the housing stands, is far too low in my opinion. And by a lack of holes in the lid can be no circulation - the warm air werweilt in large parts of the housing.
Also mentioned in the product description that the lid can be removed without unplugging the cable. But this is not at all like that. At the latest when connecting HDMI and power cables you have to pull in front of the removal of the lid selbige namely.
(Granted, the latter would now make me not for point deduction, because a computer - no matter how big -. Should really only be opened when it is off but I think that it should be mentioned)
All in all a solid case, which is to use for the beginner well.
Enthusiasts, but u. A. also want to use the GPIO interface, are with this case certainly is not happy and had better access to another, in which there is already the corresponding opening.
