Great

Great deal

Doing a project where the customer wanted these to match the wall color. Perfect match. They were very satisfied.

We bought over 1000 of these (in 25-packs) to build enterprise LAN. Findings:1) 1 Gb/s (Cat 6) transfer speeds are supported without any problems, even when you chain several of these (which is important when you build reconfigurable feed-through patch panels)2) Did not test for 10 Gb/s (Cat 6A) speeds yet, but to be fair, this product is labeled as "Cat 6", not "Cat 6A", so there is no obligation to support 10 Gb/s.3) Mounting them into the patch panel by hand is nearly impossible - it takes a lot of force, so your fingers will get tired very soon. Your best bet is to grab a large flat screwdriver and use it as a tool to depress the latch while simultaneously pushing the jack into the panel frame. You will still get tired if you need to assemble a lot of them.4) Removing them is even harder and involves a specific technique and a screwdriver again. I suggest that you don't waste time reinventing this technique and instead search for "How to remove a keystone jack from a patch panel" on YouTube.5) Overall this particular product seems to have more resistance to insertion and removal than many other feed-through jacks thanks to a more rigid and thicker plastic, but this can actually be a good thing as once inserted, these are less likely to fall out.

My first few attempts at inserting these into the Patch Panel failed because it seemed that these did not fit properly. However, after closely studying the fit, I realized it was simply blocking against the bottom tab that is supposed to be inserted inside the panel socket. As another post indicated (https://www.amazon.com/review/R1RF5ORDBM7FSG/ref=cm_cr_srp_d_rdp_perm?ie=UTF8&ASIN=B075ZPGV1H) I tipped the insert upwards to hook the bottom tab inside the socket, then leaned it forward to engage the top into the opening, and with a little jiggling, it snapped right into place. No breakage on any of the 24 pieces. Don't force anything or you WILL break something. It really does just snap right in once you have the bottom in. And it's an overall nice fit!

Works as advertised. I would purchase it again

These came in a ziplock bag with a quick-release open, and each connector was also individually wrapped in its own ziplock bag. Connectors appeared exactly as described. Although these are specifically made for keystone jacks, these are extremely convenient for combining multiple cables together in order to get a longer distance from two shorter cables. One reviewer made the comment that he could imagine these being too cheap for use when constantly plugging and unplugging cables. I don't have the experience of this type of failure to say one way or another if this is a valid concern, but I can definitely vouch for the fact that these are some great things to have lying around for someone who is just needing to get something done in the minimum amount of time and get back to the important work resulting from having a proper network connection in short order. A cheap $9.99 dremel tool from harbor freight can get rid of the keystone clip if you wanted to just have a cheaper female/female adapter.

These RJ-45 keystone inserts are exactly as described.They were packaged in 5 separate baggies containing 5 coupler's each. UL listing is on the product, as per the images and per ULs requirements. They're essentially plug & play with a 24-port patch panel, the one I chose was TRENDNet's 24-port Blank Patch Panel. The clips snap right in and align without any issues.I can't really say much else, they're pulling their rated CAT-6 speeds and are smooth when you snap in your RJ-45 cables. If you're looking for good RJ-45 inline couplers then these are it.
