The concept is a little strange because they don't actually transform (you have to actually remove the part), nonetheless I absolutely love these fossilizers. You can even use them as armor for your other transformers. My personal favourite is to combine many of them to build a "Mega" fossilizer. They are very enjoyable figures.
