More than meets the eye building bloc that’s comparable to LEGO, introduced as KRE-O by Hasbro in 2011. However in my humble opinion, the quality of plastic is still inferior to LEGO. Then again, for the price of getting KRE-O is a lot more comforting.
This basic Optimus Prime building bloc set belongs to my son and since my son is only 5 years old, I had to do the assembling of 90 pieces bloc because the toy is more suitable for children aged above 6 years old. Can’t bear to see my son carrying the box of toy in his hands hoping that he could play the blocky prime mover.
Like Transformers themselves, the set can be constructed to either prime mover or Optimus Prime G1 looking robot but the major drawback is that the toy can’t transform direct, hence disassemble and reassemble between the two modes makes it less fun.
