My son is obsessed with this, and I love it because it's meeting his needs for cause and affect play while giving him opportunities to play (practice) with real-life switches, developing his fine motor skills in a way that isn't watered down like most other toys.I love that there is a wide variety of switches and their functionalities (this is what makes it unique from the majority of it's competitors), and that the board is made from quality wood. The size is a perfect size for travel and for not taking up too much space in the play room. My son will sit with this toy longer than most, quietly focused. Only negative thing I can say is that the round rocker switch isn't parallel with the board exactly, but considering all the positives about this toy and how unique it is to it's competitors, it's a detail that I have been able to overlook easily. Very happy with this, and so is my husband and son!
