I seem to remember lots of criticism on these figures, but plasticsoldierreview.com won't mention much of them (except the missing helmet lugs).
There are too many officers and the jury is still out on how useful the tank mechanics are. The artillery set has good guns but no crew actually handling them. Are their backpacks correct? Someone suggested the two shell holders were rather Reichswehr than Imperial troops.
Well, in my view, the plastic that they are produced in is too soft to be efficient, and there aren't enough infantry poses (at least for an infantry set). The tank "crew" don't seem to be brilliantly sculpted either.
