Great little addition but its way smaller than we anticipated, even for our two year old. I guess we should have paid closer attention to the measurements in the description. For the price, we were hoping to get quite a few years out of it but he will likely be done with it by the time he's 4 or 5. I assembled it by myself over the course of 3-4 nights. Highly recommend the app to do it, although, there were a few parts towards the end that did not match the booklet (nothing major). Overall, it's nice but not the quality or size we expected for the price. In hindsight, would have looked for something bigger.
