Good storage properties, poor housing

I've been nine months now use this card in my Canon Ixus digital camera. Speed-wise, I am quite satisfied. Also videos are processed quickly with my digital camera. What is unfortunately often underestimated is the processing of the case. Since I use a lot and intensively my memory card, I often take these to the device. Already after half a year is the switch for the memory protection - the way, I never use - broken. Some time later, the case was first cracks. I use some other memory cards and I know this problem already of inferior no-name products. My 4 year old memory card from Sandisk, I've used more intensely, the body is still intact.
