Review: Great for a destructive child! - My son LOVES this car. He is 8, so he loves building things, but he is 8, so he also loves destroying things. This is the perfect toy! He built it, and can run it into walls or off tables over and over again, and it has one simple piece that flies off after a collision, and then it is super easy to put it back on! Its perfect because only the piece that is designed to come off, actually comes off, and you don't have re reassemble every two minutes!
Review: Awesome, awesome, awesome! - This was supposed to be an introductory set for my 7, soon to be 8 year old. He is just getting into Legos but the instructions were too difficult for him to do alone. Turned out very nice though with Mama's help..but I noticed a couple pieces left over after the little project was finished. Overall, it was a Great gift and great purchase. No regrets

### ⭐⭐⭐⭐⭐ This is such a robust and fun toy to build & play!
*by A***R on April 22, 2018*

This is a really robust fun toy! I (as well as my 5 y.o. boy) really liked LEGO Technic Stunt Bike (42058) because that doesn't break when kids play tough unlike regular lego! So I bought both Whack (42072) & Bash (42073) for my son & his friend. It's a bit challenging to 5 Y.O., but not overwhelming. I think it's just right amount to stimulate & develop cognitive & fine motor skills for 5~8 y.o. kids. Compared to Technic Stunt Bike, this pair run farther (less resistance after the wind-up motor runs out of propulsion), although the initial acceleration is slower. Also boys love these bad-ass racers more because they have something that breaks (sort of) when crash. You know... boys smile when something runs fast but they cracks when something breaks ;) I think it's a clever idea to include a built-in controlled-breaking mechanism.
