An Awesome product for developing minds
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
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
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?

One of the best product that I bought
I bought this for my 4 year old son, as he loves cars. Even though it is not easy to play with this on first time as this car was not ment for 4 year old, but he started to build and unbuild the car so much.We would have bought more than 1000 cars, I feel this is best among them. It's a very good activity. I recommend the 4 cars package.Only disappoint is the manufacturer does have other similar vehicles to buy again. Hope they came with new products like which I like to buy.

Worth the money
Had gifted it to my nephew on his birthday and he really loved the gift. Requires creative mind and patience to assemble. Overall a real great gift for boys from 6 to 12 year age group.

Very engaging Toy set
Wonderful concept and a very engaging toy even for grown-ups. Very elaborate and detailed assembling booklets with each set. Each is packed individually making it easy to assemble

Ok
Only opened one launcher n one vehicle set and my son is in love with this toy. It's a smart toy for kids to learn many things....Update this parts are not so strong so kids can easily break the parts while making them again n again and now we can not make two of the cars and one launcher..So if ur kids are rough handler then think twice before u buy...

Use for one time
Good concept but not sturdy enough for kids.
