I bought this product for my MacBook Air because it doesn't have USB ports and it's very hard to find one with the number of ports I need (4th generation). ). ) plus a connector for a USB-C cable, which was necessary so I could charge my computer and use an external monitor at the same time. The first device I bought (Silver) only had 3 working ports. I processed the return and ordered it in the color I originally wanted (rose gold). This one seemed to work great!

The only way I could get it to do anything was to hard reset the computer. When I turned the computer back on, the device didn't work at all. Thankfully, I was never able to get my first device back, so I was able to continue using my setup. return window.

I verified that all four ports were working, then plugged in my stuff. It worked for about 3 hours before it started doing the same thing as the second one I bought. I was able to reuse the original block,
