By Amazon Customer
This is a very good product. It's nice to be able to just drop your laptop in place and essentially have a desktop. I had an issue connecting multiple monitors. Lenovo wasn't able to figure it out. basically if you have a monitor plugged into one of the DisplayPort outputs doesn't allow you to connect a second monitor via the hdmi. It would only allow one output to work at a time. I just switched the cable to the other DisplayPort and it works fine now. I'm not sure what's up with that. But I tried the same setup on 2 different docks and had the same issue. Other that that I'm very happy with this product. Although, for the money I wish I supported hdmi 2.0 and had built in signal boosters for longer connections. It seems a little bit over priced. But I'm happy with it

5Having a dock at work is essential...
By John A. Simpson
I have been using laptop docks for years. Until I got to my current employer, I never knew how much I appreciated being able to dock and un-dock in a single motion. My current employer uses universal docks, which means you have to plug in a bunch of wires. I decided to purchase my own dock, and it has been well worth the money. I have not had any problems with the dock. If I should ever leave this employer or get a machine that does not work with the dock, I will re-sell it on Amazon. Thanks for a great product.
