If you are looking for a well built keystone, then this is the one to get. My only con is that they aren't easy to get into a wall 3 port wall plate. I wasn't successful at inserting these keystones into the Legrand 3 quick port plate, but after a bit of work I finally wiggled them into the Leviton 3 port quick port plate. I pushed mine all the way through and now they are wedged into the plate. ( I'm fine with this since this is in an area that wont be seen much). So I suggest taking your time. Despite this, I am happy with this purchase because of it's sturdy quality and heat management. I don't have a means of testing this for their capability at the moment, but I am receiving great speeds.

All of mine worked fine. Only gripe is I ordered loads of these and each one is individually wrapped. Spent some time opening them all lol. It’s for the better though.

What a great item to couple 2 Ethernet cables or to replace in a wall cover plate for an Ethernet wire that has its own plug. Just plug your wire right into the wall side of the cover plate and the wire to your device from the other side.

after fiddling with keystone punchdowns for days and having crap connections, i finally decided i'd just terminate the cables and use one of these. worked flawlessly with no discernible loss in latency.

Perfect fit in my keystone wall plate. No noticeable speed drop!
