Bumblebee is smaller than the optimus prime so it's easier for my son to hold. When it's in car form you give it a hard push and it transforms on the move. It seems pretty durable & pretty decent quality.

The plastic is cheap. Absolutely poorly made and very overpriced. Very poor quality material. But definitely not sturdy.

As a robot it is a fine toy, but as a transformer it’s fairly useless. When one part springs out, the whole thing reverts to the robot. This is a transformer that doesn't transform.

The latches are weak and will not grip so it will not stay in car form. The car is not rollable. If it does get into car form, it unexpectantly snaps a part back.
