Usually I would say 1/4 for these kind of sites but my little sister learned alot from this site, even some sutff I wish she didn't (now she bugs me that fairy's are real...) the pets are pricey and they rip you off with that pet of the month because I have overheard my sister being mad because she didn't some toy thing because she already had that pet and you had to activate it on that month.
They are pretty expensive but if you look at it like this. You only need to get one a year, they make easy to find and pretty cheap gifts that actually do something a bit useful (makes silence in the way they will leave you alone till they are bored).
Also like the guy below, the servers they use are old and don't work well, and customer service say that you need to update you flash player or system, and even after that it won't work so that is also why I dropped it from 3/4 to 2/4
