“My son received this as a Christmas gift and it's a great set overall. I can only give it two stars because both the phototransistor and the RV (which controls sound volume) don't work. The slider on the RV piece is loose so it doesn't work at all. The phototransistor does absolutely nothing to affect the light when it is covered or uncovered. My son enjoys putting these together but it's frustrating when the parts are broken.”
“Pro:High quality components.Easy to assemble and disassembleKeeps my children preoccupied for a good amount of timeCon:Requires parents to put together the projects as they are too complex for childrenSome projects are redundant. For example, merely switching a white light to a red light is counted as another project (so they are not 175 unique projects)Some components are easily destroyed by children (prism film, strobe light papers)Does not come with AA batteries”
