Low build quality, overpriced, boosters do not "connect"
The shuttle just kinda hangs from it FRAGILE front wheel onto the boosters,which are one piece unlike the real thing. Was hoping each booster individually snapped together and you could play out the full stages, but no.
Also the bay doors are loooooose and rattle around and open all the time, but then if the satellites swivel you cannot shut the bay doors. I expected them to have some way to stay closed when playing with this thing but no.
I ordered in a weekend and needed my purchase by a certain date. I was told when I ordered it would arrive on a specific day. And it sure did. Thanks so much for the great service.
Excellent product - be sure to shake-mix prior to use, the solids fall out of solution pretty quickly. So far we haven't had to use any reducer. This product is exactly what a well known structures rebuilder located in Indiana uses.
