100-Pack RJ45 Pass Through Connector, RJ45 Connectors, Premium Cat 6 Connectors 8P8C Gold Plated, Pass Through RJ45 Cat6 Cat 5 Connector Ends for Solid or Stranded UTP Ethernet Cable

works good on certain cables only

Much better than the older technology where you have to fight with the tiny wires being in the right place. You can run the wires out the end and see exactly what wire is where and these also have a higher throughput than the older technology. The crimpers you can get for these, once the wires are exactly where they should be, the crimpers sheer off the extended ends right up against the end of the plug with a much tighter, secure connection than the old ones.

These are SO EASY to use!

The pass through feature is excellent. Alas, the act of crimping and plunging the tiny blades into the wires MUST be fully done, lest the blades will protrude too far for the plug to enter the receptacle. The plug could not be inserted into the receptacle on the router until I filed and pounded each one down. Sigh. F for engineering skill. It is enough work to put a tip on an RJ-45 cable, without having to do all this extra. Some users might have raised their voices or uttered coarse oaths, but I am writing this review instead. Save yourself some trouble and buy a different brand, hoping they did not all hire the same engineering team, or review your collection of files.

Brick and mortar hardware stores seem to think these connectors are worth their weight in gold, looking at how much they charge for just a few. With these, I have more than I'll ever need for my purposes (connecting as many of my living room devices as I can via homemade patch cables) at a much lower price. No issues with connection, and easy to use with a dedicated crimping tool. There are holes in the front to let out excess wire, so you don't even need to be exact with how much of the jacket you strip off.

Does not fit cat6a shielded 23AWG Cables MAtters S/STP, S/FTP 23AWEG Shielded Cat6a Bulk is waaaay too big for these connectors - I struggled for quite some time to make a single connection, do not believe the 'upper limit' of acceptable sizes here.

Very nice connectors. I had issues using other crimp passthrough cutters other than the ones EZYUMM provides. They're cheaper and the blades a lot sharper. I kept getting shorts and bad cuts when I was crimping them using something like Klein.

I have used 6 of them with no issues. They work well and easy to line up wires in them.

It did not come as shown in a container. Just a plastic bag with no lables at all. Not sure if I got scammed with a different brand or cheap alternative.
