Product arrived in good condition. The quality of the case was good. It went well with my other. The hole saw worked as it should. Do not blunt cut a clean hole. I will keep the saw as it seems to be of good quality in case I need to cut holes for cable routing in the future.
We got a new router and replaced the cords. This grommet allowed me to drill through the back of the new shelf and route all the cables to connect directly to the new router. I had to do quite a bit of wiring so couldn't use the cover, but the grommet hole is filled in and looks good.
It was easy to drill a hole and insert a sleeve. The cables I pulled through hold up quite well and look better than just a hole. I only give it 4 stars because the hole is actually a little big and the sleeve is VERY loose. I'll end up adding some silicone around the grommet to hold it a little more securely and prevent it from popping out when the cables are pulled.
