Better for entertainment center
Size: 6FT, Style: 1 Pack
Have it mounted under my workshop desk the mount ability is simple and works good also have my phone plugged in and the ports work good, the length of the cable is good if you want it somewhat far from the outlet only thing is I wish with the design they spaced out the outlets since ryobi’s charging outlets are bricks but other than that zero complaints

Perfect Power Strip Outlet!
Size: 6FT, Style: 2 Pack
Perfect! Great Quality. Outlets are spaced closer together, but it has 12 outlets, which is amazing for our needs.

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.
