5 stars: It really works! very good basic features like allowing to set up the desired test-file size. it is very helpful to let you know if your microSD is original or NOT. Thanks to the developers.

4 stars: It is probably good, but it didn't tell me anything as to whether the sd card is good or fake. It is not very user friendly. I have a 256 gb card that it tells me i have 268.4 gb total and 267.88 gb available. The youtube video on how to use the app is a joke. Just someone pushing buttons. No spoken words. I gave it 4 stars because it was free. It just need better instructions.
5 stars: Was able to find options quickly because the application UI is very intuitive. I like it that I can run any of the most important tests necessary to understanding what's going on with the SD card. Unfortunately, the application showed me that I purchased an SD card that is slow. I need to learn how to backup the card and replace it with a faster one. Good job on the application guys (and girls). :).
