A Perfect Gift!

I mailed this as a present directly to my nephews and I have been told it was one of the favorites out of all the birthday presents! I think I will send my niece the origami box once her birthday comes around.

Amazing!!

I thought this product was great value for the money. It is a science kit with step by step instructions, real wooden parts, an activity booklet to explain some principles. Overall really good. I just wish that you could fit it back in the box when finished- but its so big! My son uses to box to store his matchbox cars now, he loves it and carries it with him everywhere. Go figure!

Don't worry about it breaking

The materials used to create the excavator were easy to use and made of the highest quality. My son is very heavy-handed, so I was a little worried about him breaking it, but he didn’t!

Straightforward + Simple

The instruction booklet was straightforward and simple to understand! My daughter was able to complete this kit in no time. She LOVED watching it move after everything was built; I hope to find more kits like this for her to try!
