Absolute no-go product

Initially none of my mircoSD cards went right into the slot, since the dimensions are simply too small.
After stuck several times we went, but only with considerable effort, what if the microSDs
so look also may represent the end for this. When pulling out one breaks off his fingernails.

But then came the disillusionment, either the microSD card is not recognized or the adapter hung in describing just from the OS from.
I tested this with one 4GB & 8GB SDHC Transcend 4GB SDHC Sandisk, 16GB SDHC Samsung & 4GB SDHC ATP. As OS Windows 7 & 8, Ubuntu 4.12 & 4.14 and Android 4.1.2 & 4.4.2 was used.

Therefore, there remains only the conclusion that part is absolute and therefore shot went back again.
