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.

Decent install power strip
Style: 20W_USB-C, Size: 6FT
I really like this search strip as I installed the inside of my RV the only problem I have with it is if you were using bulky transformer style plugs like that of a iMac laptop, charger or other big transformers, you will not be able to use the USB outlets in the center and I don’t know if that’s by design to limit current flow, but it sucks.
