I have all three and I would recommend them very highly! However there is a common flaw on Forager,(Kickback). The grasshopper wing, when you transform from bug to bot you have to be VERY careful. The way it is designed is basically a plastic "C" that folds in around itself to lock the wing in position. It is quite common for this to break. It still holds up and everything but is broken, on mine anyway.
FT does even mention that it is a very delicate piece and to be very careful right in the instructions.
