Summary: Great item. I ordered two in order to have multiple Ethernet connections in the office and bedroom for TV boxes, Roku, Security cameras, computer ect. They worked perfect. Unless your running 100Mbs or above, these will work just fine. I wouldn't hesitate to get more in the future.
Summary: Maybe it's because I'm old, but I expected this switch to be about the size of a 4X6 index card. It's actually closer in size to a business card, and just thick enough for the connectors to fit inside the casing. The "wall wart" power supply is actually heavier than the switch itself, which means I can put it just about anywhere I want. It works fine, and has given me no problems at all since I purchased it.
