They work and get the job done. I wasn't pushing any boundaries with only 1080p signals though. The flexible cable inside was handy since in-wall hdmi cables aren't as flexible and it made it a touch easier to connect inside. The mini 4 inch cable as it attaches to the faceplate is a bit odd though. It's not a snug clip, as there's maybe about 1cm of play where the connector can move "in and out" while clipped to the plate. The cables connect reasonably securely to both ends of the extension, but the extension itself wiggles back and forth in the faceplate. You only notice it when plugging or unplugging cables. Unnerving if you're not expecting it since it feels like it's going to push through, unclip and get lost inside the box/wall, but it hasn't unclipped on me.

Works perfect.

Easy to install. Works perfectly!
