my roommate got one of those as a gift from a friend. Honestly, the triops are kinda cool and they get rather large (the two that ate the rest were about dime sized). You may have seen the tiny white dots, but they actually end up the size they appear on the package.
Unfortunately, for their eggs to hatch the need everything to dry out then have water reintroduced, they're presumeably one of those desert dwelling organisms that just pops up in puddles when it rains once a year.
Don't rag the triops till ya know em, though, they're goofy as all hell. Not everyone wants to deal with keeping a healthy aquarium but still want to see neat little things swimming around. I can't fault them, aquariums are a lot of money and work. triops are not.
