content: We bought this days ago, and it is already going back. An impromptu stop at the store for a walker for my 10mos old to take on vacation so he wouldn't be cruising all the furninture at grandma's house. After three kids, I was missing the old ones I had for the other two, but was tempted because of its simplicity and "no battery" thing...let me break it down:*time consuming assembly, had to hunt down screwdriver*it tipped over immedietly as the baby pulled himself up, so it only worked when I held on to either him or the front of the walker, making this not an independent toy*within minutes mailslot doors came off*now have to hunt for "mail" so it can all go back to the store*the "adjustable" traction worked on some floors in our home, but not all of themon the plus side, it doesn't run on batteries, is pretty basic and the baby loved playing with the mail slots while the doors stayed on. Either way, I am returning it and getting a different activity walker for him.
