We are on our second one and we would never be without it. I can take the girls to the mall and all the stores in it without being booted out, simply because they are not running around on the floor. When we go inland to shop, it's really hot in the summer and just too hot for them to walk on the sidewalks even with shoes on because their little bodies and faces are so close to the pavement where the heat rises and just "carrying" them isn't an option either and I don't want to leave them at home simply because strollers are silly or some such nonsense.
The stroller is wonderful if they have bad knees, or are blind like my little Delsi was, or are seniors who just can't walk too much, or it's crowded where they could easily get kicked or stepped on and so on.
My husband even pushes the stroller without any hesitation and he's a big man at 6' 2" and 190 lbs. He said they do have their place and it doesn't matter to him what people think as long as his little "princesses" are comfortable.
