Fine, Be Careful How You Mount It
Size: 6ft Cord, Color: 20W_Black
Good power strip with the functionality that I needed. 12 plugs and usb. Be careful how you mount it because the plugs on one side are upside down. You may have to buy thin pigtails which I did.

So far so good...
Size: 10ft Cord, Color: 20W_Black
I bought this for a work space where coworkers kept stealing the charging blocks needed for essential equipment to use for their phones and unplugging essential equipment to plug in their phones. So far after a month the issues leading to it's purchase have not returned and the unit hasn't as yet developed any of it's own. I'll report back if the latter changes within the year.
