These digital flash cards are pretty handy for reviewing the rather complicate Thai Alphabet since one need not carry a deck of cards around and they're free!
Here's warning though to those who, like one reviewer think it is a complete language course. It isn't. No alphabet flash card set is, nor is ever intended so. They function as a tool for learning the Alphabet and numerals, and with 44 consonants, 24 vowels and 4 tone marks, with many letters which vary very little from another, one is definitely in need of any tool that can help.
I read with varying degrees of fluency, about 23 languages so I feel I know what I'm talking about.
A couple suggestions: it would really be good if the mnemonic were spoken as it flashes and I think the pronunciation of the numerals should be animated along with the 1,2,3 etc. you already animate for ๑,๒,๓ etc. along with the recording of the number being spoken.
