First of all, it is a quite large track. Like other similar tracks, it requires a lot of space as it remains a single piece after assembly without the possibility of "packing" it for storage. So if you have a small space, this may be a problem.
Otherwise, assembly is easy with relatively simple and clear instructions. Just make sure not to make the same mistake as I did and stick the stickers on the relevant pieces before proceeding with assembly. Otherwise, the stickers may give you some trouble.
As mentioned in the description, it only comes with two cars inside. For us, this was not a problem as my little one already had a big collection of Hotwheels and we almost filled all the available slots!
The "dragon" that falls could be attached to the top in a slightly easier way for the child. It is not necessarily "difficult" to secure it on the top by itself, but sometimes it takes 3 or 4 tries until it "locks" into place.
The tracks connect properly with each other and there is no problem with the circulation/launching of the cars.
Overall, in the almost 2 weeks that we have had it, my little one shows no sign of lack of enthusiasm (yet) and spends a lot of time playing with it. Maybe even more than we expected.
In general, it is worth its money, and the only drawback (which is not significant enough to lower the rating) is the way the "dragon" is supported.
If you have a child around 5 years old with a "big" collection of Hotwheels and, of course, have the necessary space, buy it without hesitation!
