All EZRJ45 connectors eventually fail because they are open on the end allowing environmental contaminants to corrode the connection, don’t use them.
The number one reason the EZ connectors fail is a dull blade on the tool, which tends to not cut well.
If you keep a sharp blade, and then seal the ends with something like clear fingernail polish, you'll be amazed at how well they will work.
As a test, I used some EZ connectors on SCP cat5e with SnapAV extenders without sealing and got no thrill. Sealed the ends and all was well.
