Prussian Elites are a Good Addition
I have been very happy with this item. I like HaT's strategy of making a separate set with the specialty units so that the user can decide how many to include in their army. I like the softer plastic that was used for these soldiers, since my son uses these soldiers as toys, and the softer plastic reduces the bending or breaking of protruding rifles, arms, and legs.
I had a little bit of trouble getting the flag-bearers to remain standing once assembled. I wasn't sure which way to point the flag to balance the soldier. I ended up putting a few drops of bondic on the opposite side of the soldier to balance the weight, which works well enough for me.
A more skilled modeler likely could have assembled the flag-bearers to stand on their own, but I lacked the patience for that.
