We purchased two Creative Kit subscriptions for our 7-year old twins for Christmas and, boy, do they love them! They are thrilled when their CrunchLabs delivery arrives and can't wait to open and begin assembling. The projects are challenging - requiring attention to directions - but absolutely do-able for elementary age kids with some adult support nearby. Our girls are so proud of themselves when they finish their kit and spend hours playing together with their new activity.
These STEM/Engineering-focused projects are exactly what we needed... a move away from the same old "toys" and something they can really dive into, build, to discover a love of making/prototyping. Best find I've had in years. We've shared our high praise for these activities with many friends who have young kids and they've followed our lead to introduce their own kids to these fun boxed kits.
