I ordered 2 kits
I ordered 2 kits, and got a great offer on a 3rd, so I ordered that one also. Got both sets in less than 2 weeks, and even got some freebie specials added, which was great. I can't give them 5 stars. It's true they're not 100% on the parts. The first small robot kit I built, one piece was missing from Step 1. Not a good way to start. So far I'm though the 2 small kits, i was able to rig the piece I needed. But if you don't have extra parts, you might be stuck.
