What makes it special?

MitchElectronics kits are designed with education in mind and as such use high quality double sided PCBs. The through-hole plating of each pad means that even the most novice of builders will not be able to tear traces or break pads (unlike many other professional kits which only use single sided boards to save costs). These kits are also RoHS compliant which make them safe to use and no kits use non-RoHS components such as LDRs (which contain Cadmium).
