I've used the punch down version of these several times. They work.

These don't work. The toolless clip that's supposed to push the wires into their slots....simply doesn't.

Save yourself the trouble, get a punch-down

Having used punch-down units for years I thought I would try these. What a pain. I'm going to back to what works.

This is the new version with build in clamping. It's more convenient and the individual wires are not bend 90 degrees like the old version. However this also lacked any support of the cable going in, leave all the support to the exposed individual wires, which bend 90 degrees at the base of the entrance.

Excellent and easy to use.

The ones I received did NOT match this picture. It still works but is a big hassle to get all the wires in where they're supposed to go. The tolerances are very tight.

Easy to use and terminate

Like other reviewers, I got something that looked nothing like what is pictured here, but still thought it might work. This weekend was the big cable running weekend, and of course they didn't work. I'd steer clear of these.

Monoprice support was cool about it though, so ordered the traditional keystone kind and a punch down tool and hopefully all will be well.

More difficult than just going old fashioned and using the tool. Might be easier for someone with small hands. Just grab a tool and some old style keystones

The wiring works, but I find the device that locks the cables in keeps falling out.

If you're new to running RJ-45 and want to save money by not getting a punch down tool, look elsewhere. That was me. First time running RJ-45 and figured I may never need a punchdown tool ever again.

The idea behind this product is to seat the wires in the correct spot, then clamp them down into the connectors. In theory, it's a great idea. In practice, clamping things down does require a tool (the included plastic lever isn't enough) and the connectors don't cut into the wire jackets enough to create a strong connection. This literally requires a tool and still doesn't actually do what it's supposed to do.

I haven't saved any time (I've spent 2+ hours troubleshooting this) and unless I can get a refund on these, I'll end up spending more money than I would have just getting a punchdown tool in the first place. In top of that, a project I was hoping to complete today probably won't be finished until next weekend since I'll need to order different keystone jacks as well as the punchdown tool.
