"Overall, a great set. My 11 yo daughter was turned off by the popstar line of Friends and was ready to abandon the theme. But she loves this set as is, and is already planning to replace the green and pink accents on the coaster with more blue and purple to turn it into a bobsled themed ride for the Winter Village.
As others have noted, the cars keep falling off the track. That's the only big problem with the set, but it certainly is significant.
The drop ride is also fantastic, although a bit short. I suppose making it taller would have compromised its sturdiness. She has had no problem resetting the ride by lifting the seat part straight up and letting the pole spin in place -- much simpler than spinning the seat back up.
She will also soon work on motorizing the Ferris wheel. The parts are on order! As a parent of a girl, I'm pleased to see that LEGO included controllers and gauges in this design. It's important to me that my girls sees herself as in control of mechanical things, not just a user or passenger.
Can't wait to get her the rest of this line. I might have to get an extra hot dog stand for myself!"
