This cable was the PERFECT solution to connect my computers to the power source. It is very sturdy, durable, and has a very nice design. The polarized plug was easy to install and worked flawlessly .As my tests showed, the cable has great conductivity and i had no issues with flickering screens or any other glitches. The only downside for me was the length, which was a bit shorter than what I anticipated. But overall, I would highly recommend this cable to anyone who needs a reliable, efficient and cost-effective option for their computer set-up..
