I bought some along with play dog (thinking it was a diff brand but still like play doh) for my DS.
OMG that stuff is horrible, it doesn't make any shapes - if you manage to get it into one lump, as soon as you touch it, it explodes into a huge crumbly mess!!
DS had 3mins playing with it before I threw it out, and I don't think he was sorry to see it go either... He helped me clear it up!
