Building Experience

Assembly Instructions

[This review was collected as part of a promotion.] My son loves it, he's a big Mega Wrex fan. If your kid is younger, expect to have to help them assemble it. Really fun to build though!

Smash and Roar! (Well, please don't smash it!)

walmart.com

[This review was collected as part of a promotion.] My son is 3.5 and adores this set. It is compatible to Lego brand- quality-wise, but I think it may be a little cheaper price-wise than Lego! Would highly recommend this one. It was a lot of fun to build together.

Love This One!

[This review was collected as part of a promotion.] Fun for kids that love building blocks and monster trucks. The directions were easy to follow. My six year old really liked how it can be a race car or a monster truck. You can add additional sets to mix and match and customize vehicles.

Two Toys in One

Mattel Shop

[This review was collected as part of a promotion.] I received the MEGA Hot Wheels Mega Wrex Monster Truck as part of the Play, Rate, Review program. This toy is an excellent building toy that has just the right amount of challenge for any young one building it! There are two forms that the vehicle can take once built. You can build it as the monster truck itself, or change the wheel base to be much lower and more like a standard race car. The parts and steps were divided up by numbered bags, making it easy to follow and complete with not having everything opened up at once, and the instruction manual was simple enough for all ages to follow and see how to build it. Some parts were a little tough to snap together due to being smaller in size and hard for smaller fingers to pinch together, but otherwise there wasnt any major difficulties to the building process. This is an awesome toy for kids and adults who love building toys and hot wheels alike!

Easy and fun to build!

[This review was collected as part of a promotion.] My son is absolutely obsessed with legos. He received this as a birthday gift and he loves it. It is great that he can take the time to build it and then get more play out of it by driving it around and even switching the tires for more off roading. I highly recommend this set.

Great largo set!

[This review was collected as part of a promotion.] Easy to assemble, my kids love it and it's one of their favorites to play with. Once the box arrived they couldn't wait to play. I helped them when they needed it but it wasn't that difficult for them.

Keeps my kids entertained!

[This review was collected as part of a promotion.] Lots of fun for my 7 year old son; he enjoyed it with his other Hot Wheels vehicles. He set up a course for the cars to go on and used the small ones to go over with this monster truck and had a great time.

Good fun for use with other Hot Wheels vehicles

[This review was collected as part of a promotion.] The overall set was good and easy to build. I liked the tool that came with that helped separate the pieces. The pieces were nice and were easy to put together. The mini-figure was a tough to sit on a building piece.

Awesome review

Mattel Consumer Services

[This review was collected as part of a promotion.] While this monster truck buildable is extremely cool, it does take quite a bit of time to build and there is no way a five year old would do it. Dome of the shaped pieces that are not super flat do come off easily so be on the lookout for that.

cool

[This review was collected as part of a promotion.] So much fun! We loved this toy. My 7 y.o. Put this together mainly on his own. He did have some trouble figuring out what piece was what, and deciphering colors on the instruction sheet. We love that the blocks were separated into stages of the monster truck. He really enjoys playing with the truck!

So much fun.

MEGA Hot Wheels Mega Wrex Monster Truck Vehicle Building Set with 187 pieces, featuring a teal dinosaur-shaped monster truck with giant black wheels, a poseable micro action figure driver, and extra wheels to convert it into a race car, compatible with other MEGA Construx building sets.
