If you are on a budget and get an offer with a price up to 60 EUR then it is worthy for the newest generation only.
Do not buy the first generation which you can recognize based on the package description "30 MB/s". Hands off! Don´t buy it!
Because I had purchased two pieces which had the same issues after the same time of using I think it was no particular case.
Perhaps not the whole series was concerned but because SanDisk offers two newer generations in the meantime it isn´t worth the risk to buy an older version and may lose excellent photos or other important data.
Tip: some vendors are very carefully with their statements about the maximum size of memory cards or do not update their website.
For example Smartphones like the Samsung Galaxy Note or the BlackBerry Z10 had the capability to use memory cards with a size of 64 GB right from start.
It´s your own risk if you buy a bigger sized memory card as the vendor recommends.
But in worst case use the microSDXC memory card with the SD Adapter in your digital camera or MP3 player or as a backup storage for the notebook.
Side benefit: because of the higher performance of this microSDXC memory card you can make faster serial photo shoots depending from the capability of the camera model.
Memory Cards from SanDisk with "Android" in the product name are not produced for Android Smartphones only!
There is a software tool stored on the memory card named SanDisk Memory Zone to manage your storage.
You can find this software tool also at the Google Play Store to download and install it with your Android smartphone.
But much of the reviews at Google Play are not very positive so I wouldn´t install it if I would use an Android phone.
Instead of "SanDisk Memory Zone" I recommend you Explorer from Speed Software Ltd. and DiskUsage from Ivan Volosyuk.
