I have some copies of its predecessor, with whom I was pleased (of 10 plates was a broken, all other work reliably). Here I expected a much flatter variant according to the pictures, but that's not the case, there is a perceived difference of one millimeter. If you compare the USB3 ports together, it is found that the plate was turned upside down in the Ultra, you put the terminal now reversed into it.
For 2.5er I find the noise as well as its predecessor relatively loud. You can see the board no longer stand on the side edge, because the sides were chamfered.
So no great advance. After all, the price has dropped.
