Review on 🔘 Adjustable Diameter Plastic Grommet for Cord Management by Chris Anderson

At $4 you can't get any better. My new iMovr table didn't have grommets so I bought them. The 3 1/8 size fits perfectly and they perform like any other desktop hub I've seen. I don't understand the reviewer who complained about the hole size. If the cake cutting holes you choose aren't big enough, you can just leave the insert out, SOP for grommets.
