I have used sandisk micro sd cards for a long time and have never faced any issues with it. They are durable and lasts long. I specially chose the 16gb 100MB/s since, I was looking for using this on my raspberry pi 3 b+ board and install Kali Linux on this card. Though they work alright I see the read and write performance was still a little bit sluggish compared to Samsung Pro+ that i also own. However this is priced very competitively hence, no complaints and besides I was not after high performance read/write ops.
