Here is one of those things I just had to have. Let's unpack it and put it together to see if it's gonna be what I want or not. HInt: it's heavy...
 

It's got wheels but different sizes. Can you guess what I am?
 

And I have legs with two more wheels. These two wheels are the same size as two of the others on the above picture.
 

Here you can see all of the wheels and should be able to tell what I am.
