I had bought a bunch of flash card and used in a row and all I know its not working well, after you burn card, moaquito take breaks for a minute and came back. this is how its working for me, so I really dont found that card is usefull at all. I bought this flash card thought it would be less harmful for our small kids but still its not working good if they put some more effort then this card can be harmful to ourselves.
its not userfriendly as I know, its just not good for using, however Im still using my rest of card everyday
