Review on 5-Pack White VCE UL Listed CAT6 RJ45 Keystone Jack Inline Coupler - Enhanced SEO by Djkutt Kent

Bought 2 packs of 5, I've used 5 so far and one of the 5 was defective. I ran a cable through my attic into a patch panel and then into a switch and got disconnects and very slow 20Mbps speeds. I tried replacing everything in the chain except the adapter as I didn't understand that a bad adapter could cause slow speeds. I figured it just wouldn't work so that was the last thing I checked. I wasted a good hour and a half of my time with a bad Keystone clutch. As soon as I replaced it with another one, everything worked beautifully, my internet speed jumped from 20Mbps to 175Mbps and there were no more connection issues. Worked 4 out of 5, 4 stars.
