This socket module is exactly what I needed to protect my equipment from power surges. As my tests showed, it is very easy to install and the illuminated feature is a nice touch for when I need to quickly identify which outlets are in use... the quality of this product is very high, which is important in an industrial setting. The only con I found is that it`s a bit pricey compared to other similar products in the market. Overall, I highly recommend this socket module to anyone in the industrial and scientific field looking for reliable circuit protection..
