This is now my second Ultrafine LG 5k - the first one went bad after 3 weeks. Not sure if it was just a dud, or they seriously have issues. I just returned it to Apple. That said, I absolutely love this monitor - The resolution, everything about it (except for the fact that the old one failed.... and I'm hoping that this one doesn't) -- It's also well worth the price.

As a newly minted father (and designer), I can tell you that the nipple is not very intuitive at all.
