We got this for our 4 year old for Christmas, and the handle he holds on to while jumping is so shaky. The screws are constantly coming loose, and now the one screw just keeps turning and turning. It will not tighten up. My older son had a different brand when he was younger, and never had a problem with it. I should have went with that again, but I thought this one would be better cause normally I love the fisher price brand.
