I keep thinking that Kre-O are just cheap knock offs on lego. But my mom thought they were neat and said I should buy one. So I buy the Megatron one, because just to replace the DOTM Leader Class Megatron that is not gonna happen. But whats the point when the vehicle itself does not transform, you have to take it apart and build the robot mode. The only thing I like about this set is I only like the Shockwave minifigure. Then just today when I was at toysrus, they actually had Sentinel Prime. I thought "Big Deal" but then I saw a Soundwave minifigure. Probably the only set that includes a Soundwave minifigure. So I don't know, I kind of hate Kre-O, should I get Sentinel for Soundwave? I know for a fact that when kids buy lego sets, like Ninjago or Star Wars, they only want them for the minifigures. Is that the same with you guys? Do some of you only want Kre-o sets for the minifigures?
