I personally think that the size, the durability and the potential is well worth the $30. Izzy is only 21 months so she's pretty hard on toys and so far it's held up to her. She loves going in and out of the door waving "bye". She jumps on the pillow I put inside to peek out of the windows. I can see her playing with it until it falls apart and I know we'll get another one to replace it. Why spend $70+ on a plastic house when this one will give your child much more. It's affordable and it gives them a creative outlet and can be folded away to store. They can color the pictures outside or make they're own pictures on the inside of the house. It comes with 8 markers but I got an additional pack of markers for more color choices.
If you have the space I would also suggest that you use packing tape on all the corners and tabs to reinforce the stability. I also plan to find a piece of cardboard to tape the house down to to make a floor. I think it's well worth the money. Just keep in mind that it is made out of cardboard and will eventually fall apart. I love love this house!
