My daughter still really enjoys the Jungle gym, she has used it for about 4 months (she's 7 months now). The elephant stopped making music after a month or so, just like many other reviewers commented. Also, never leave your child unattended, as the folding problem (see previous reviewer) also occurs here quite often.
Lastly, I wonder whether all the plastic toys and components are BPA-free. I an't find any information on that on the website and you'd think that a company would use that as a plus in their promos.
