Fantastic engineering

Awesome holder. Follow the directions. This appears to be German manufactured and very well thought out. Great having my rig off my desk - more room for my second monitor!

Pay Attention

Pretty damn good, instructions are on the right in English. Took me a hot minute to find it and was so close to getting back into Duolingo and learning German.

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.
