This is a great Star Wars Lego set for the money. The going rate for this set is around $20.
It has 244 pieces with very clear instructions. It is easy to put together. It took my son maybe an hour to put it completely together.
The model itself is very stable when finished. The model has great details to the real thing, like it has side mounted weapons and an opening pilot hatch. It also has a knob that you can turn to make the cockpit rotate side to side and side, which is a pretty neat feature. It does not stick and rotates easily.
This set also comes with one AT-ST pilot with a helmet and blaster.
As far as a the play value I am not sure. The legs do not move so it is pretty much stuck in one pisition. I suppose a child would come up with ideas how to play with it even with non movable legs. It is sturdy enough for children to play with.
As far as our family goes, my son has it displayed on his shelf with the other Lego models.
