These work well. Make sure you don't put too much current draw on it. In my case I'm using it just for a keyboard and mouse. When I added a 2.5 inch HDD it stopped working. Re-read the instructions and sure enough power draw is the problem. BUT - it still works well for my application as long as I don't expect too much power delivery.

Very good product

Size: 2 ft, Style: USB-C

This is the second one I order. This time, the blue LED light is so weak, that is difficult to tell it is connected. But it works, and works very well! I would buy another, if I needed it.

Great for adding USB ports to any USB-C device.

Size: 0.7 ft, Style: USB-C

I needed this to allow for more USB connections on my laptop. It is totally compatible with any USB-C device. I like the small blue LED on it that shows it is powered on. It's very small and lightweight and inconspicuous in design. Love the value for the price.

Great replacement screen for an old Chromebook

Size: 15.6" 1080P

Needed a new Screen for an older touch-screen Samsung Chromebook that bit the dust. Repairing it wasn't an option since it's no longer available. Enter this gem of a portable monitor. It works great. Not a replacement touch screen, but works fine with the chromebook touch pad or mouse and dongle. Easy to hook up, a bit testy on first several attempted to bluetooth connect, but works fine now. The speakers leave a bit to be desired, but I just use Bluetooth speakers anyway. Overall, very pleased with the screen clarity and responsiveness of this portable monitor. 15" screen. Great value! I'd buy it again.
