Since it’s pretty much a foolproof technology at this point, look at the reviews on Amazon, especially the critical/low rating ones and see if you can overcome whatever it was that the reviewer didn’t like.
Hykon is one of those unknown/lesser-known brands on Amazon that have a surprisingly large number of high rated reviews, over 4.5 stars average.

i like modularity so I probably wouldn’t buy an all-in-one unit for myself but I’d definitely consider it for my parents or the house in general. They’re pretty sleek looking and household friendly.
