Pick Which Creation to Build Out of 3 Choices.
This is a nice build. It didn't take long to build (½ hr, give/take). I got this for my son when he was 10. The 3 in 1 sets are great because my kids can decide which of the 3 things they want to build. Now these sets share the pieces for all 3 different builds, so that means that all 3 things can NOT be built at the same time. The creation/build has to be taken apart and then simply follow the directions to build something else using the same blocks. Not all 3 builds will use all of the blocks, so there will be spare pieces. Legos are always fun and it keeps my kids occupied for a little while and gives them something fun (& creative) to do other than mindless TV. Overall this is another great set from Lego. We have a lot of Lego sets and we're usually very happy with them.

My son loved it
Anything Lego my son loves. The fact that this was a 3-in-1 made building it all the much more fun for him.

Awesome for kids and adults
When I was a kid, Legos were things you assembled and reassembled into different objects. These days, most Legos are a set that gets put together once and left as is. I love that these show how to make three different objects with the same set. It it a great blend of Legos as they used to be with Lego sets as they are today.

Super fun and affordable
I bought this for my nephew and he absolutely loved it. He's a big lego kid and this is a lego that he was amazed for the design and the functionality. It really is a fun, cool lego set. I couldn't ask for a better Lego set at this affordable price.

Lego Creators are fun because its 3 in 1.
My son already has a few Lego Creator sets, so it was no surprise when he wanted to order this one. He likes the fact that he can create a robot and then if he gets bored with it, he can disassemble and create something new with the pieces. Lego products are already priced alittle high, but what I don't like is that sellers on amazon get to reprice products and sell for a high price because certain products are discontinued at the stores. We paid more for this product now then it was originally sold for. Overall, the my son was content with this robot he created.

Another Fun Lego Creation
Grandsons love Lego sets and this one is no exception!

It's a good Lego substitute.
Instructions are pretty good. My six year old is able to read them and put them together. Keeping him focused is another question, but that has nothing to do with the toy. The prices for these types of toys seems too high for what you get, but that is true for Legos, too.

Great birthday present!
Bought this for my sons 5th birthday and he LOVES it. The age is 7-12 but my 5 year old could do it without much help- he’s pretty mechanical for his age. Not sure how most 5 year olds would do with it. He loves that he can take it apart and make another one as well- he’s made all three!

My 6 year old LOVES this set. He loves that he can make three different lego builds out of it, and we used the LEGO Instructions app which made it SO much easier for him to do it himself. It was a really fun build (x3!).
