トランスフォーマー：コラボレーション×ホットウィール - エルセグンド

Didn't expect the robot mode to hold a pose this well, but the joints are tight enough that mine's been standing on my desk for a week. Converting it back and forth takes maybe ten seconds once you get the hang of it.

I grabbed this for my desk and the 5-inch size is just right, not too bulky next to my monitor. The transformation from robot to car is smooth once you figure out the sequence, and it holds up after dozens of flips back and forth.

The convertible gimmick actually works smoothly, no sticking or forcing it. My kid plays with it as a car for ten minutes, then flips it into robot mode and starts making up battles.
