Please do your research. Unfortunately I didn't and it cost me thousands. I've spent weeks (and thousands of dollars of work) running my business with this cable. It wasn't until we finished wiring that we realized we were getting 1-9 Mbps (and often no internet at all). We found something strange was going on with our Ethernet switches. After testing everything, we tried another brand of cable that we had. Of course - 300 Mbps (the actual speed of our Internet service). This cable is not as advertised. Choose the best brand and save tons of time and money. We need to re-route all of our wiring throughout the company. Very upset.
