When I first saw the Labo Preview demo a few months ago, I immediately went to Revain and pre-ordered. I have a 5 year old son who is very interested in science experiments and building things (Lego, Magnatiles, etc.). We received the lab last night and jumped right into it. We worked as a team and decided to build a house. It was a long process as we carefully followed the instructions, but it was a lot of fun. My son could do a lot on his own, but he really needed help. The process was very simple but it took almost 2 hours to complete. We had Labo for a day but here is my first impression. That's great! If you have a young child, maybe even older, you should get this. This is a fun educational experience best shared in a group. Making the project was fun, playing with the end product was also explosive. There's even a discovery mode that explains the science behind how projects work. There's even a science lab sandbox mode where you can invent your own designs! I recommend Labo with 5 stars, my son gives 6.
