The media could not be loaded. First of all, when the product arrived, the box was bent as if it had been opened before and the pieces were strewn around the shipping box (see photo). Fortunately, nothing was missing and I didn't have time to get another present for my son, so I just shoved everything back in the box and wrapped it. The box was unsightly but I successfully disguised it with wrapping paper. Although the box for this item says age 9+, I doubt any 9-year old could build this by themselves. If you buy this, be prepared to spend multiple hours "helping" your child decipher the instructions and build this product. The instructions consist of only pictures, some of which aren't that clear. Two of the pieces were outright defective -- one end of the stick was "bald" so it wouldn't click into the connector piece -- so I literally had to fasten these pieces together with tape (see photo). I didn't take photos of the bald pieces before I put the tape on them. There were no extras of the defective pieces so I just had to make them work. For several other pieces, the snaps don't hold tight, so when the roller coaster zips by, or if someone bumps the structure, the pieces come unsnapped, so we are constantly snapping stuff back together. Also, one piece broke, but I was able to work around it. Finally, the final product has several design flaws. When we built the track exactly as stated in the instructions, the roller coaster car kept bumping into one of the "walls" and stopping. I was able to tinker with the track and reconfigure it so the car no longer hits the side. However, as you see from the video, the car does not roll around the track continuously by itself -- it needs "help" when it gets to the bottom, and this was true even before I reconfigured the track to fix the wall-crashing situation. My son (6 years old) and I had some good "bonding time" building this, even though it was tedious and he complained a bit. He was proud of the finished product and enjoys playing with it, but this is not something most young kids will be able to build by themselves, particularly with the defective pieces, design flaws, and unclear instructions. I was prepared to help my child because he's 6 and the toy is marketed for ages 9 and up, but even if your child is older or very advanced, the issues I mentioned above make this a challenging build, even for adults.
