Bought this for my grandson, purchased it early (hugs mistake)- fast shipping, great seller, manufacturer sucks . . . . emailed them twice that there are 8 parts missing - nothing, tried to get contact information ie . . .phone etc, cant find it. Clearly they are not US based and you get what you pay for - its junk. I had one of these when I was a kid and this is not YOUR erector kit or anything even close to it !!!! Bottom line, dont waste your money . . .quality control went the way of US manufacturing jobs . . . . gone forever. Guess I will just have to be happy with the box of parts I have that wont build anything . . . . thanks for nothing !!!
