Review: This is such a robust and fun toy to build & play! - 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.
Review: Fairly easy to build - My children enjoy these LEGO pull back cars. They work well. Children 8 and younger will need assistance to build. The directions are easy to understand, but if the little ones miss a step or aren’t good with visual directions, they may miss a block or use the wrong piece. Otherwise, it’s a pretty easy build. Definitely fun to play with. I enjoyed playing with the cars myself. I purchased 2 other styles of pull back cars. Great STEM project for primary grade kids.

## Questions & Answers

**Q: What can I do about a missing piece?**
A: Hey there. If you've double-checked everywhere (packaging, build, floor, etc.) and a piece hasn't appeared, don't worry! It's easy to request a replacement part. Just go to LEGO.com/Service and choose the "Bricks & Pieces" option to get started.

Kind regards,
Emily
LEGO® Service

**Q: Is a manual included? The box implies the instructions are only available online, & I'd rather not print out 50+ color pages . . .**
A: The instructions for 42073 BASH! are included, but the instructions to combine this item with 42072 WHACK! to create WHACK! 'N' BASH! are only available online

**Q: What to do if package was damaged when received?**
A: Return to Amazon for a replacement.

**Q: Is this tough enough for 13 yr old boy to play with after building?**
A: I think it would be as long as they are not overly aggressive with it. However, we bought it for my at the time 6 yr old and my 10 year old helped him put together. I don’t know how much enjoyment a 13yo will get out of it.

### ⭐⭐⭐⭐⭐ Good value, great gift for the creator in your life.
*by N***S on December 1, 2019*

Bought this for Christmas for my nine-year-old grandson. You can't go wrong with Legos, right? Give the model extra tricks and features, and it's sure to be a hit. I especially liked that it was a kit of some substance for a reasonable price, and this one can bear out lots and lots of use and reuse. With a lot of sets, they're tiny one-hit wonders (put it together and forget it); not really worth the jacked-up price. This one doesn't fall into that category, and, man! Does it look cool!
