This was such a fun project for my 11 year old's birthday. He did about half on his own and half with me but only because he wanted to do it together. He could have easily finished on his own. It's way bigger than I expected - 2ft or so? Well with the price.

Easy to assemble. Great quality. Each section of the puzzle was exciting and kept me engaged.

Fun build. Took a little while to complete. It's big!

Very good quality. Authentic looking. I have 5+ 4D build sets they are all fantastic! The only cons is the cardboard punch tool.For the new product lines 4D builds finially realized the importance of a plastic punch tool!

This one took me just shy of six hours to build. It was so fun as always. I have so many of this brands puzzles.

So this 3d puzzle of the original 80’s Optimus Prime is pretty cool and gives meNostalgic vibes that I welcome. I hesitate to call this 4D as the only thing that makesIt 4D is the 2 small LED lights that are used As for the headlights. Other than that it’s just a cool 3d puzzle. Still don’t regret the purchase

De buen tamaño y las piezas se unen perfecto,es exelente para un coleccionista de Transformers las luces prenden por USB

A really cool model to put together. It's made out of a foam with gloss paper printed on it so I would suggest having an exacto knife on some pieces and cut them slice them out not to chance damaging it. It's a great kit to put together and fun. I really like that this model comes with lights really adding something to it. I would highly recommend this to any Transformers fan especially of the original designs.
