Almost perfect, but probably as close as you can get for under ten bucks. I would give 4.5 stars if Revane would allow it. I used two to hide the 35 foot LFE (subwoofer) cable - one where the cable enters one wall and the other where the cable exits the other wall. This will keep the holes looking clean and professional. The only thing that would make them a little better would be if the cylinder had some raised ribs. It's pretty slick and fairly slick so you'll need some caulk or glue to secure it in place if you're going to use it in Sheetrock. If it was slightly ribbed you could tap it in with a rubber mallet after drilling the 1" hole and it would snap into place. If you're wondering if an HDMI cable will go through, I'd say probably not. Just to see, I tried with the HDMI cables I'm using. It's just a little too small. I'm using a fairly thick HDMI cable. Maybe one with a thinner fork would fit, but it would be close. Banana plug speaker cords and RCA cords work well as long as you have enough length at the breakout so you can plug in each plug (red/white, +/-) individually. A good solution for cutting holes in the walls for cables.
