## Customer Reviews

### ⭐⭐⭐⭐⭐ An Awesome product for developing minds
*by C***Y on 29 December 2023*

The media could not be loaded. Initially I was a bit skeptical. The packaging was pretty good and my son was able to assemble the vehicles in 3-4 hrs. I found the documentation to be extremely good and thanks for this out of the box initiative of creating these kind of DIY toys

### ⭐⭐⭐⭐⭐ DIY toys that work very well
*by N***T on 22 August 2020*

The media could not be loaded. A very good toy!! I have been buying a few of these smartivity toys. They are good quality. DIY helps engage the child in building their own toy, and also good functionality.These set of 4 cars is good too. We built one of the 4 cars and the launcher and it looks pretty good. Tires are smooth running, and the launcher ensures the car goes farther than expected. It isn’t Hotwheels, but very good.I am very satisfied with these toys.Only point I feel is that there are lot of rubberbands that need to be used for building the toy. This could possibly be a bit risky if not handled well and can injure the kid when building the toy.Otherwise i think this are really good quality toys.

### ⭐⭐⭐⭐ Over-priced, but good.. Speed from the launcher could be better
*by R***Z on 23 May 2023*

It's good, over-priced, but good.. Also, the speed is too slow.. Hardly 2 feet while using the launcher.. How can the speed of the vehicles launched from the launcher be increased? I tried using a high tension rubber band, that didn't work.. Any other ideas that can be tried out?
