I don't normally buy other brands of building blocks but this set was at Target at such a low price I couldn't resist. It's a $25 set that was marked down to $2.26 plus tax. It's got 335 parts and you can make a robot or a car. It doesn't actually transform, which is kind of sad. I hadn't bought any KRE-O sets before but I had looked at them in the store and Erik had brought a couple of the smaller sets to a TCLUG meeting. He'd gotten them for free at a Transformers meeting. They seemed better than Mega Blocks but still not as good as LEGO's pieces. After building the robot I thought they weren't too bad. They clutch power is much better than MB but still not quite as good as LEGO's. The robot actually held together better than any Mega Block set that I have purchased in the past. MB had a line of robots at one time. I got a couple of them at Target on clearance and built them. They were awful. Just awful. This Bumblebee is much better than that. The robot is actually fairly poseable. I could get him to balance on one foot. The little ball hinges have balls coated with a black rubber like substance. They are fairly stiff to move. This set is aimed at the 7-14 age group and I think that the hinges might prove a bit too stiff for the younger end of that group. I had trouble getting a grip on the body to move the legs or arms without almost always knocking off a another bit here and there. I'm not a car fan and building robots isn't something I'm that big on. I thought the car looked fairly good but the robot not as much. The minifigs are mixed, both in design and quality. The yellow guy looked ok but the guy with the black hair looks creepy. The other weird thing is the color difference in the yellow parts. They look pretty yellow in the picture at the top of the post. When you open the box you see the yellow part with a good bit of orange tint in them. The robot on the box cover isn't even as orange as the parts were. Now that I have dragged the box around to the two clubs I belong to, then built the robot, I'm not sure what I'm going to do with it. The river? Maybe. There aren't enough parts for me to care about and I won't want to mix them in with my LEGO. The river covers up a lot of sins.
