So I've tested several mini PC's over the last year, wasn't really expecting much out of this one. Kind of figured it would be about the same as the J4125 units. However, I did notice that this one seems to have a bit more oomph then the others. Not much more mind you, but for sure a slight improvement. Considering the price of the unit which is right in line with the others I tested, and in a couple instances, even cheaper. I'd for sure recommend it if you are looking to get into the mini's. Oh, and before I forget.. One thing that sets this unit apart from others, is the ability to use a 2280 M.2 rather than just a 2242. The best part about this u55 though, is the fact you can run MACOS Monterey on it just fine.
