Easy to install for clean under-desk mounting
Fits my Dell WD19TB dock perfectly. Great for under-desk mounting (just be careful if your desk surface isn't super thick - you may not want to tighten the screws all the way)

Overall great
I LOVE IT. omg exactly what I was looking for. Easy to set up. The only issue is you have to bend over/kneel to set it up and in the process I got an upset stomach, which is why deducted one star. So if you have bowel issues like me, you might want to consider that with this product.
