They were purchased for security cameras and within a year this is the third one that has broken. While no one has touched them (the cameras are located at a very high point), they suddenly locked up, the camera itself cannot format them nor can it be done from a computer. Never again.

After 1.5 years I removed it from the camera that was not plugged in, and it was destroyed! It locked and I can't delete or format. The good thing is that the videos it has recorded are playing back, but never in the past has a memory card been damaged, neither by adapters, nor by mobile phones, nor by security cameras. And neither did this camera damage a previous Kingston card

Attention to opening the package as there is a risk of breaking the card! It is better to use scissors to open the package.

Very good product. With the previous card, stored files were occasionally destroyed. This one works perfectly.

With the TAPO TPLINK cameras that I have had for a year now, they are okay, not exactly a speed test but they are durable.

The best thing I have bought in a microSD card. I have put it in a camera where it gets very hot during the summer, and it works perfectly fine, while others couldn't handle it and would break. I will buy it again if I need it
