Review on King Innovation 95015 AlumiConn Connector by Christopher Clearfield

This is exactly what you need to replace sockets, switches, etc. if you have aluminum cables at home and cannot afford it in the house been made to repair them. Although expensive, they are MUCH cheaper than renovating an entire house. However, they are very difficult to integrate into existing framework conditions; But on some electrical engineering blogs I found some good suggestions for the most compact connection possible.
