Yup, they are ridiculous. They look ridiculous and you feel ridiculous pushing one....and YES I have one
It only gets used at fairs & festivals, where there is alot of activity and alot of people walking around. I just think it's safer in that environment (and it gives me a place to store stuff I don't want to carry).
It also came in really handy after ZoE's spay. I zipped her in it and rolled her to wherever I was working around the house, so she was near me.
