Simplicitic, fast, and amazing quality
Size: 6FT
It made a big difference from wireless connection to wired connection. Definitely worth it for online gaming and casual movie nights. A good amount of thickness that doesn't tangle when installing and pretty easy to use. I would buy again for future devices. 10/10

Bridging USB-C hub for Mac.
Style: 10-in-1【1 HDMI+1 VGA】
Best USB C hub for a Mac. It also has interface that bridges the technology crossover for the boomers and millennials 🙂 (SD, Micro SD, RJ45, 3.5 mm audio)

Every day essential
Style: 10-in-1【1 HDMI+1 VGA】
I love it. It’s very useful for my computer. It is very well built and is durable the connection seems lose but works very well. Very easy to use. And pretty quick. I use it for my mouse and keyboard. It works very well without any noticable delay. I do not know if it can charge a computer. Mine does not use it to charge. But it works perfectly and would totally buy again

VGA compatibility issues
Style: 10-in-1【1 HDMI+1 VGA】
My Asus laptop could not sync the display scaling properly with a Samsung 1280 x 1024 VGA monitor connected via the hub. So compatibility is not universal. Seems great otherwise.

Good durability
Style: 10-in-1【1 HDMI+1 VGA】
I had the 8 in 1, but realized I needed one more usb hub for my current setup when using dual screens, scanner, printer, and drives, this seems to do well, is a bit heavier than the previous model as expected. Good material and easy to unmount quickly from the computer. Works with usb c connections so perfect for my Surface Pro 9.
