Daniel Robert, Netherlands
We have recently started subscribing to circuitmess stem boxes to replace another known brand. The difference is night and day. Circuitmess provides fun projects for kids to enjoy. We have completed two projects and are looking forward to the next one. Albert and the team are always on hand to support and provide help if you need it. Well done team.
