It's good to see reusable energy and organic products being used nowadays (there should be more of it) so I guess this set was a fantastic idea! The instruction manual is full of interesting facts and info, thus making it very educational. The build itself to be honest didn't take as long as expected, and I can't remember the last time I had a set where you either emptied all the bags out together or sorted them into brick types, colours etc as nothing is numbered! I went for the 826 pieces in one pile just for the challenge!! My only improvements would be that the baseplate is quite thin and as this is tall it has a bit of movement, maybe a thicker baseplate of a few bricks between the house and the turbine for extra strength would be good. Overall it looks good and promotes renewable energy but my opinion is it is a bit overpriced.
