I have developed a deep dislike for UI overall through the years due to their many missteps (see: most of this thread), but those little PoE-powered 2.5G switches are amazing and I am surprised that while 2.5G is getting more and more popular, no one has any real competition for this product. No matter, I bought three!

I do wish they were even smaller (I've got one location I'd like to mount one inside a wall box, which is admittedly pretty niche), and I am never again touching UI's configuration software (even 10 years later I feel that wound), but, yeah... love these little guys.
