Great little power strip.
Size: 6 Outlets, Style: Desk Socket - White
I used this in my garage as a battery charging station for all my cordless tools. BONUS that is has USB & USB-C that charges my flashlight and phone when I need to plug in! It's super easy to mount.

This product is great! I bought it to mount under my new desk. It comes with two-sided sticky tape which worked out great. Now all my cords are hidden! perfect.

VeryUuseful!
Size: 6 Outlets, Style: Desk Socket - White
The first power strip that you can put anywhere. The convenient brackets let me mount it upside down on my desk and out of sight. % plugs, with one to accommodate a large plug-in power supply and USB ports.

Works well
Size: 6 Outlets, Style: Desk Socket - White
It works well but I've been having issues with the USB slots because it seems like it is not providing consistent power flow. Otherwise it works fine and the mounting kit is a nice addition
