Are RJ-45 Passthru Connectors Best For Bad Eyesight?

Actually these do help with bad eyesight. Even is you don't have bad eyesight sometimes the colors of the cables are sometimes hard to differentiate. Especially the white with the colored stripes depending on the quality of the cable. Personally I don't like these connectors as I have gone in after the fact and the cable ends were not cut clean. This is due to either a dull blade or not aligned properly. This is why they have keystone jacks and patch cables. I understand sometimes you need to terminate cables with RJ45's but I prefer not to if possible. There are some new modular devices that make this really easy such as one from Signamax. Kind of bulky but much more reliable. There are other brands as well like the new keystone modular plugs from Beldin.

A “Plug” from “Jack”?

i love these

I used to hate them, figured it was the "Easy Mans" way of doing RJ-45 connectors. Then I started a new job, and all they used were EZ-RJ45 connectors, of the pass through ones. It was a pain to get used to them at first, but now, I kind of like it.

I do have bad eyesight, but that's what my glasses are for. I never had a problem with the non-pass through connectors, but now I find it does make checking your conductors are in the right order, and quickly fixing if necessary. Another guy I work with was also always very against them for the same reason listed in the main post,

 have hear plenty of criticism around pass-thrus being prone to sloppy installation problems like jack shorting and not fitting due to badly trimmed ends

But I've only seen that problem when people don't make sure the connector is snapped all the way into the crimper, or use the wrong crimper, or don't change the blades on their crimper. I've done a ton of ends with the pass through now since late 2016, I have not personally had a problem for the most part. We had one model of Honeywell camera where the ez-crimp connectors didn't like to fit.

I would have no problems going back to regular RJ-45 connectors, but I don't buy them, so I use what I am supplied with.

I'm not a fan of the cost of the connectors, but that's my only beef with these things.

EZ-RJ45 connectors definitely help me out - eyesight isn't shot but I wear contact lenses and it saves me from needing near sight aids, also helpful in situation of poor available light and less than favorable ambient temperatures. 

I've also found it helps me in prep work in that I can hand off the job of prepping one end to someone else and come back to terminate in bulk later.  All they have to do is thread them for me, then I'll can just check colors and crimp.
