Our Premium Plug & Fly components are delivered assembled. "Assembled" and "P&P" means that end customer needs to put together pre-assembled components and do the wiring for USB, power supply and backlighting as well as cable connections between components. You will need screw drivers and other basic tools. Soldering is not necessary but you need basic knowledge of electrical. In general assembly is easy to do and does not need any specific training. Anyway be careful when working with electrical parts.
Our Home Series components need to be wired and assembled. Soldering might be necessary for sidebase assembly.
