my daughter, 9, loves this set. there are two problems to be aware of -1. her fingers are not strong enough to snap the pieces together, so she needs an adult's help. and2. when she built the catapult she noticed that when it swings down, it is unsteady and the sensor picks up the floor. she says the design is flawed, and so she built supports along the side and under to keep it more stable.as a parent, i can think of one negative, in the app on the tablet, there is not a good explanation of what the arrows and categories mean. my husband had to look on the internet for a booklet to explain what the app features didnow that you know those things, i would say those aren't such bad things and the overall enjoyment from building and using the robots have far outweighed the negatives. the pieces are well made, options are plenty, and having the app at all is very handy.

Acabo de recibir mi pedido. Me percate que los sellos fueron violados y al abrir la caja me percate unas piezas no vienen selladas como si estás hubieran ido reemplazadas

My kid loved this.

App doesnt sinchronize with robot making this completely useless. Do not waste your money.

This was a birthday gift for my grandson, and a gift that he had requested.
