I bought this for a beach trip for my 9 month old baby at the time, but we never got around to assembling it while we were there.  I just recently broke it out for playtime for my now 14 month old in the basement and ... wow! I'm so confused as to why I let it sit around unused for so long!! It's a snap to put together - even for the directionally & manually challenged. My daughter likes it - one thing I can say is that when closed up, the airflow is obviously a bit stuffy, but she can easily tear down the front flap when she wants - she quite enjoys it.  (I have not yet used it outside so perhaps the airflow factor is a good thing in the cooler weather months.)
