I bought my first Kemper (used unpowered rack) in spring of 2018. I liked it a lot, but was having a little trouble with the workow. Set it aside for six weeks or so and was planning on selling it. In the meantime I played plugins. I decided to plug the KeKper in one last time to see if I should really sell it or not. And within about fifteen minutes realized it would be worth the effort to adapt to it's workflow. It's the one modeler I've had (other hardware models include an Atomic AA3 and Helix LT) that I have grown to like more and more the longer I've owned/played it.
I don't use it at home only. It really depends on what you mean with home use..... If i was someone that just plays 15 mins of guitar after work, i don't know if i would have paid the money for a Kemper.
