Hot Wheels Mario Kart Circuit Track Set with 1:64 Scale Die-Cast Kart Replica

I bought the product from Amazon japan but it came with unusable motor, kinda sad 😢😢. Plus it takes months to get to me cus I'm in Malaysia and this set is not available here so it hart to find a replacement part

[This review was collected as part of a promotion.] My son received this for Christmas and was very excited to get it going. Unfortunately the cars keep falling off at the tower section of track, you will be lucky to get a couple of complete laps. The fit and finish at the tower to motor driven section is poor. I have noticed the climb at the tower is too sharp an incline and the twist is too tight leading to the cars failing to make it round. I have no idea how this made it past R&D or any form of quality control, the design team must be either careless or negligent to the production of this set and are unfit to fulfil their role.

I bought this for my son last week to add to his hot wheels collection and I hate to say, but I am very unhappy with this track. On the tower curve the cars keep flying off the track and we can't keep them on. It's making my son upset as well. Also the track won't sit flush it the mario extensions at the meeting points so it halts the movement of the drivers. I love hot wheels, but this track is one I do not recommend to anyone.
