I took a chance on the b-stock and it looks and works like new. It drives dual HDMI monitors on my Windows laptop without issues. The only minor thing is the box was a bit beat up, but the dock itself is fine. For the price, it's a steal.
I was worried about compatibility with my Mac, but this dock worked flawlessly. I connected two monitors and had no problem with display output or USB peripherals. The 60W charging is enough for my MacBook Air. Great buy!
The dock works initially, but after a few hours, one of the monitors sometimes goes blank. Unplugging and replugging the USB cable usually fixes it, but it's annoying. Might be a b-stock issue, but I expected better since Plugable is a reputable brand.
On my Windows laptop, this dock is perfect. Dual monitors work great and the USB ports are fast. On my MacBook Pro, it also works but I had to install a driver and occasionally the ethernet disconnects. Still a good hub for the price.
This b-stock dock looks brand new. Setup was easy: just install the DisplayLink driver and connect. I now have dual monitors at my desk, and everything runs smoothly. The power adapter is a bit large, but that's minor. Highly recommend for anyone needing a budget-friendly dual monitor solution.
I bought this specifically for my Chromebook, but it didn't work. The monitors never detected, and the dock wasn't even recognized. I tried troubleshooting with no luck. I returned it. If you have a Chromebook, look for a certified one instead.
The dock works perfectly, but the b-stock unit I received had a few cosmetic scratches on the top. It doesn't affect functionality, but if you care about aesthetics, you might want to get a new unit. The performance is solid: dual HDMI monitors work great, and the USB ports are useful. Overall, happy with the purchase.
