I expected so much more from a step2 product. The assembly was horrible. It calls for a screw driver but you defiantly need a electric screw driver or else good luck. There are no preset holes just little dimples and your expected to use a regular screw driver to get past all the plastic. The mobile broke instantly when trying to assemble. My neighbor bought the same product for her daughter and had the exact same issues. It’s okay when finally assembled but you gotta work for it.
