[This review was collected as part of a promotion.] My 10year old loves this! It is easy to assemble and fun for hours. It’s very durable and you can do many things with the pieces. There are small pieces so be careful with little kids. The whole family has had fun with this!

[This review was collected as part of a promotion.] I just bought this set for a friend we worked on it. It was cool and interactive. It was not to hard to assemble for a 5 year old. Just a fun way for a kid to concentrate for a bit.

An all around great set. It has a good number of fun minifigures, has a great color palette and I dig the little references to Bionicle and Exo-Force. My only complaint is that this set has a lot of stickers. They do a lot to give the set its overall feel, but I get paranoid about how they’re going to age.
I would recommend this to a friend!

Great Build with Fun Easter Egg

I love this set, but ironically not for the coaster itself. It’s overall a fun build in and of itself, but the mech suit was what sold me on it as I don’t typically collect coasters. BUT, the mech suit brought me back to my childhood as it’s a callback to a theme long-forgotten by many. Of course I’m referring to EXO-Force! I absolutely LOVED that theme as a kid, and the Stealth Hunter (7700) was my first of MANY EXO Force sets to collect! 💙 It’s wonderful to see LEGO paying homage to themes from our childhood!
I would recommend this to a friend!

Such a fantastic build with lots of great details. The set is sturdy and sparks a lot of creativity in my 6 year old.
I would recommend this to a friend!
