Review: Good quality. Works great. - These are very well made. No complaints. I used them to connect my patio TV to my Sonos amp about 150-feet away via an ethernet cat5 cable. It works great. I did use an optic to analog converter on the TV so that may have boosted the signal but that has nothing to do with the quality of the connectors. I will buy again.
Review: Expectation surpassed. - Splendid
