I was so exited to get these for weekend trips but when I opened the box. Poof!, I found that they are both about the same size.  The advertised pictures are 'Tricks of the trade' as they say.  They would be good for smaller children going grandmas' / may pass for small travelers. The wheels are of not good quality either.  Also when one is placed on top of the other they are not as sturdy and they squish haphazardly.  NOT WORTH the price, you could get a lot more for your money if you shop around.  I sent mine back within a day or two.
