Raspi delicately push in the lower part - click -, put the upper part, with gentle emphasis - click - done! It's almost boring, nothing to screw or hone ;-)) The fit is very good, the case is made clean, all connection ports are properly seated. The GPIO pins are easily accessible. The micro SD card can be without scratches o. Ä. easily switch. Due to the many openings, the heat dissipation is not a problem. I suspect, however, that the Case frequent opening / closing can not stand, but what also? One comes ran outside to everything, even the heatsink could easily be retrofitted with the help of forceps.
Only the appearance is of course not the best, who needs a show object, should choose another case.
