The simplicity of it made it beginner friendly and great as a group activity. The page has links to all documentation and parts needed so we were never stuck about what we needed. The pcb's design was very clean and easy to work with. Andy was also very quick about getting back to my messages and was very helpful with the whole shipping process. Everyone had so much fun and despite the majority of us not having prior soldering experience the success rate was 100%. We're all happy with the little gadgets sitting on each of our desks.
