I absolutely love this product-- it's my second time purchasing it! The first purchase, I left at my old job in great hands. For an entire year, my kids went above and beyond to create awesome things. I trust that this year at my new job, it will be the same. With a larger class now, I purchased the larger kit and "tinkering station" has been a hit. Worth every penny, and will be getting another set for my tot once he gets a little older! Perfect for hand-eye coordination and fine motor skills.
