Not worth the money!
This is a scam they don’t have nearly as many flash cards as they claim. Better off using real flash cards instead.
Response from developer
We do apologize. The original description did have an incorrect (inflated) number of cards listed. But this was not intentional and has been corrected. This set matches the same number of flash cards in our spiral-bound set. We hope you have found them useful and have been successful in obtaining your sleep credential.
