Review on Pasow Speed Adapter Control Switches by Julian Locklear

I bought two of these Bc. I needed a good hub to charge my devices. Right now I can only use about 4 plugs from each hub. When I add more, the device "charges" for about 60 seconds, then pauses and moves on to other devices not wanting to charge. So it's not about the cable, the device or the plug. This is the device as a whole. It would be great if they actually worked. I would think I had a defect if I only had one. But both hubs behave like this, and even when connected to my Mac, most devices don't show up. Maybe 2 from each block. Total waste of money, save up and buy something better.
