Good fit and nice sharp holesaw included
The hole made by the included holesaw was the perfect size for the insert. They work well and cosmetically look much better than a raw hole in the wood. I tried the cable wrap and inserter and both make the job of wrapping and securing the cables much easier. Overall a good product and a good value.

Great for small projects. Nice fit.
I purchased this set while building a couple of end tables. They fit like a glove and it's really nice that they come with the hole saw bit. It's a great set for what you get.

Includes everything you need and a bonus to get the cord wrap
I bought this to route the cords up to the monitor on a height-adjustable desk. The top of the desk is an inch thick, and this was easy to drill through. To make sure I got a clean cut and did not damage the top, I put painters' tape on the area where I wanted to cut and drilled a small starter hole to get it exactly in the right spot. It cut a really clean hole from the top, and the plastic insert fit perfectly.
Once I got the hole cut and the wires run where I wanted them, I put the cord wrap on. The tool that comes with the cord wrap is really slick and super easy to use. I was able to bundle together three cords that hang off the side of the desk. Given that the desk is adjustable, it was a nice bonus to get the cord manager with the kit, as it keeps the cords from getting hung up in the desk when adjusting it.
I'm very happy with the purchase, great price.

Good product
The hole covers are great. As far as the hole cutting bit. Not so much. But still worth the price.
