I was so excited when this arrived at my door! I could tell immediately after opening that the product was sturdy. It did take me a little bit to assemble but i am not the best in that department! Once it was put together my two year old couldnt wait to play! She figured it out fast and has had hours of fun with it! My 10 year old has even enjoyed playing with it along with her. We have only kept this product in the house so far but i can tell that if we do decide to take it outside it will be so easy to clean! Over all i am extremely pleased with this product! I have reviewed the wonderball fun house as part of the toy tester program, all veiws and opinions are my own. Thanks again step2! We have yet to be disappointed by one of your products !!
