Perfect set. It came with a USB with good instructions too!Wow - lots of parts and no assemble directions like an actual Lego toy will have. Nothing is on line! Many of the bricks are irregular and they do not fit together well or at all. This should be easy to pull off with minimal care from the supplier! My grandson loved this but assemble was not the fun it could have been.This is easily the worst brick build I have ever encountered. No instructions were included. I had to contact the seller separately to obtain a pdf. The diagrams are some of the worst I’ve seen. Very hard to follow. I’ve lost count of how many pieces this set was missing. Easily 10% or more. Final structure is so unstable it’s practically unmovable. My son wanted this set so badly for his D-Day mock but I wish we had never purchased. He would have been better off building his own set from scratch.First of all it came with no instructions I had to contact the seller for them. It is extremely difficult to assemble My daughter has to help my 14 year old grandson with it- he is very proficient with assembling LEGOs and Cobis on his own. The only way they could keep it together is with LEGO glue. Very dissatisfied!!! I would give zero stars if possible!!!
