I use a UHK daily. Can't mitigate those concerns, but I can provide my experience with it:

1) I enjoy it enough to carry it when I need to. I found a softshell case at a music shop that fits the UHK and my laptop surprisingly well. Not addressing preference, simply noting that it is more portable than other split boards I've used.

2) The UHK is built well and very sturdy. I've never questioned its durability as it's constructed better than most of my other keyboards (except for maybe my Leopold).

I use it enough that I've proposed getting a second one. Not because I'm worried about production or failure, but because it is a good keyboard and I use multiple computers. Though with the portability and a few cons (addressed in my other lengthy comment), I've held off from buying another for now.
