Phillips products are a good value because the quality of each product is exceptional. I have automated lighting inside and outside my home with good results. My outside lighting equipment partially shut down; that is why I purchased this adapter. Before doing any other troubleshooting, I assumed that my 3 year old adapter had failed. It was one of three I had installed along with eight Lily lights and five Calla lights. When I received this order, I went out to trace the line back to the supposedly failed unit. Upon disturbing the line, I apparently serendipitously re- established the connection in one of the T connectors, resolving the problem. I did not use the just purchased adapter and decided not to return it, it now serves as a back up should one of the units fail, could be used to further expand my system. I know it is of good quality and the price I paid for it is fair. Shipping was prompt. Kudos to the seller.
This power supply has been rock solid so far, and the cables are well constructed and waterproof when correctly installed. Retail price is $100 or so, and too much in my opinion. Buy it on eBay!
