This set arrived from TCP yesterday and I am very happy with it thus far! The jet modes are solid and nice, and the individual robot modes are stronger than expected. Concord/Silverbolt is the weakest of the five (although fine), which is sadly to be expected since he does the lion's share of forming Jet Commander/Superion; the others are quite poseable and each has a good deal of personality. Materials are exactly what everyone has said, sturdy and weighty. Cannot wait to combine them after work tonight! My fiancée immediately claimed Harrier/Slingshot as her favorite (she likes his head).
