I upgraded from the Up &amp; Down coaster that my son grew out of and got him this for this birthday.  It was a huge hit at the party with kids from 2 yrs to 6 yrs.  It is fantastic quality (keep it outside and it holds up great) and both my kids use it every time they go in the backyard.  It is also a hit with the neighborhood kids.  It is worth the $$.  Would recommend for outdoors as it is quite large and pretty high.  Also the kids go so far when they go off the end.  Had to keep moving it back b/c they were hitting the fence :).
