Defective products, I will explain!

These cards have the following problem after many insertions or extractions into an SD card reader.
To the left of the card is a slider switch. Said switch when unlocked in a fully upward position will allow your PC to delete files on the SD card.
When the switch is in a downward position it is locked and your PC cannot modify the files on the card.
When you insert this card into a card reader in a totally upward or unlocked position, the slider moves ever so little downwards. Even half a millimeter is enough, and your pc cannot modify the files.
In theory all the way up is unlocked and all the way down is locked. This is not true, an infinitesimally small distance downwards will also lock the card.
I have tried many ways to keep the slider all the way up, such as a small amount of tape, or using a toothpick to insert the card to ensure the slider does not move. Out of 5 tries, one is successful. But this is a huge waste of time.
I have three of these cards and all three have the same problem.
