"Mainly for toddlers and preschoolers. Get lots of tracks and some engines. Don't get too many destinations - these are just expensive distractions. 5th graders will occasionally help build for the young ones."
"Kids 6 years and older with technic experience can build the models while adults write and load the programs. Don't expect kids to work independently on this set until after 9 years. Robotics are fun for boys."
"Get this if your child is crazy about How to Train Your Dragon. Hiccup and Toothless are too big to be played along with other dragons. Wings do fall off during play. (The designers decided to save cost of shipping and packaging by having detachable wings.)"
"Red Death is a must have to go with the other set. Unfortunately it is much smaller that Toothless from the other set. Feet and wings, and even tail, fail off often during play and storage. Frustration factor is high."
"Good building experience - has portcullis and draw bridge. Include minifigures of a king and his knights and 3 invading enemies. The finished castle is actually small and not very impressive looking even though there is a lot of play value. Falls apart easily when moved because there is no big baseplate or foundation like the older castles. Parts made in China."
"Believe it or not, my boys played with their cousins for an hour with this set. The mixer was squeaking but worked. The molds were great. Beware though, at the end, you will just end up with one color sand - pinkish light purple."
