This company has a website which is packed with good in depth technical detail. There is fairly good introductory material. I have a feeling that it is not always that easy to find a product if one is not sure of the exact description. I was looking for a powerline adapter and originally I was not sure what these were called. However, once found there was lots of information to help me understand what would be required to make a purchasing decision. I wonder if a brief description under the products would be helpful on the products page? Otherwise a very useful source for information and guidance.
