"This isn’t your average LEGO set. You’ll have to download an app in order to build them. The set seems intimidating to build and use. It’s not hard and geared towards young kids. The build process is simple. Just follow along using the app. It didn’t take long to build the robots. This is a very educational toy in a way. Teaches programming at a child’s level & it’s a cool learning experience. Playing with the robots are fun as we have hardwood flooring so they moved along quite well. Don’t be intimidated by the product. It’s really fun and perfect for those of all ages!"
