The units looked really cool and were of excellent quality. They popped up reliably albeit slowly which was fine with me. I was really looking forward to using these in a built in cabinet we're making but they did not fit where I wanted them so I had to send them back. I would buy these again if I ever had a project that needed them.

Good buy and very useful accessory as a cut in on a table.

Model: Pop up outlet-black

Bought these for a new built in enclosed patio buffet table. Everyone always needs plugs for phones, computers, iPads, etc. This is perfect and cover recesses to minimize exposure although mine is not exposed to outside weather.
