The case is very well made and it is completely transparent. Also the cooling was thought at the bottom of the box there are air vents. After the Pi's use can be seen all good and the Pi is well secured. In addition, rubber feet may also be supplied with which the case is very safe and non-slip on the table.
For this price you get a good cases, but you can not use the GPIO pins. Since I no longer bothers you, I give still 5 stars.
