LEGO Technic WHACK! 42072 Building Kit with Pull Back Toy Stunt Car, Popular Girls and Boys Engineering Toy for Creative Play (135 Pieces)

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!

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 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.

It’s a Lego building kit. Boys will love to assemble it and play with it. It runs. And it can be combined with other compatible Lego kits.

I wanted to take a quick minute to share my review of Lego technics! My kiddos are huge Lego fans, but unfortunately, large Lego creations are not entirely suited for multiple moves or constant traveling. However, we recently purchased a few of these for our own children, as well as for gifts, and. They are AWESOME! After building his race car, my third grader was actually able to RACE his car (and jump it off of the dining room table 😳), and it has remained intact. In our house, that’s a BIG deal ❤️.

Gift for my 8 year old nephew who loves LEGOS. He was very pleased!!

Both my sons 7 and 4 years old loved the lego technic whack set, I bought two this green one and the red one that goes with it so they could race them or smash them together, the engines fly out which is neat. They like them more then just the normal lego sets because they move and can be played with and aren't as fragile. Definitely would reccomend!

There are no better LEGO sets than these Technics. They are a little harder to put together but totally worth it! My son is 7-1/2, so on the low end of the 7-14 age range but he still put it all together by himself. He loves the pull-back feature. These Technic LEGO sets are more durable than other sets which is a plus bc my son is really rough with them. He loves dropping them from counter height to show everyone how tough they are. When dropped on the wheels they don’t shatter and come apart. He has broken an axle once and we found you can buy those separately if needed. He has almost all the under $20 kits. Planning to buy them again to make the combination builds. Those are super cool looking!!
