I never used one but have talked to people who have and they love
them. There appears to be none of the problems you asked about and a
big plus safety feature of this type of child carrier is that if you
should crash your armsdo a lot to protect the child. Another thing
that's great about these carriers is that the child does not have to
lean over to one side in order to see around the rider. That makes any
trip much more enjoyable for the child plus the rider can see what the
child is doing at all tmes.

My next door neighbor has this one http://www.amazon.com/dp/B0048MB82A
which attaches to the stem, not the top tube.

You want to install it on a bicycle with as long of a wheelbase as
possible. He's got it on a Schwinn city bike and it's crowded. His kids
have just about outgrown it as well, it's for babies, not toddlers.
