Works great, just plug it into a USB port and the DisplayPort and away it goes at QHD (2560x1440). Every once in a while (fairly rarely) the monitor's input seems to turn off and on, but it's not that big of a deal.

Works great. It allowed me to connect my mini Display Port graphics card to my 30" Dual Link DVI monitor.

Works as advertised. Looks pretty good. Works great between 2018 MBP and Dell 30” dual link dvi monitor

I bought this to work with my Dell monitor and Macbook Pro to replace the Apple model that was having problems. I still get the same screen fluctuations but not as often. As this is the only model I have found (Apple does not make theirs anymore-- you can order and it won't ship), I assume I have to give up on this Monitor.
Non-powered adapters do not give the higher resolutions that I need in the 30" monitor. Could it just happen to be a defective model? I don't think so.

I bought a Yamakasi Catleap Q270 27”, so i needed this to use the monitor with my MacBook Pro. It’s a quality product & it works great!

I used this adapter to connect my 2017 MacBook Pro to my ancient 30" Apple Cinema Display, because it's still in great shape and this was cheaper than a new monitor!

Ordered this product mid March and have been using it no problem until this past week.

My computer will not detect the max resolution of my display when this adapter is connected when it did before. Tried resetting graphics drivers, restoring my system, and using different cables to no avail.

PROS:
-Works great if you need a temporary solution
-Inexpensive compared to other options

CONS:
-May fail without notice

Works as expected with an old 23” Cinema Display and a new MacBook Pro that has only USB C

Excellent product. Costs almost half as much as the Apple product and worked just perfectly.

I have a Apple Cinema Display with a DVI connection that was considered vintage and unusable. I had tried several different combinations of adapters to connect to the Apple MiniDisplay. This was the only product that provided full resolution allowing well functioning hardware to continue to be used..
