*by D***D on 19 April 2025*

### ⭐ Poor quality
*by T***T on 24 May 2025*

Item was missing a wheel. As the size of the toy is small, the missing wheel is rather noticeable. Better quality control is needed

### ⭐⭐⭐⭐⭐ He loves it!
*by S***E on 14 June 2025*

These are my son’s favorite toys. He takes the spider one everywhere. He’s 5yo and can easily transform it. The little arm comes off but it’s easy to reattach. The build quality could be better. My son has so much fun with it and I need to buy more. The size is a good size. Not too big and not too small.
