I have an UHK now and love it so much that I bring it back and forth to work everyday. Before the UHK I had a MS Sculpt and was a bit worried I wouldn't be able to get used to the UHK so I used Karabiner to set up a mod later and pretrained myself for a couple of weeks before pulling the trigger. Once I got the UHK the learning curve wasn't bad at all. For people who maybe tried a split keyboard and couldn't deal with it I would recommend the UHK since it's mostly the same as a regular keyboard.
