And to add: Very prone to braking so finding good ones second hand can be tricky. There is also a version with a 2x8 as the bottom plate and 2x4 for the top. Comes in the classic base colors: yellow, red, blue, grey, white and black. Yellow and red are most common, followed by grey. I have never seen a blue or black one but apparently they do exist.
