I use SOHO Mk3 in my RV because of its USB cellular support and WiFi wan ability plus it runs right off 12v no problem.
I was very surprised by the coverage. It is buried in a cabinet and if I crank the power up to high and put boost on my devices will prefer connecting to it over my houses inside router from across the yard through a concrete wall. I have to remember to turn down the power when we get home. Its very annoying Peplink doesn’t publish the WiFi transmit power specs on the SOHO like they do on most others, its actually a good selling point as its obviously very strong.
I was also surprised how easy it was to setup, for all its features the UI is simple and effective, it makes sense and just works. It could use some updating but not a big deal.
It been extremely reliable for me except for one flaw in its WiFi wan implementation, if you don’t use that then its pretty much hands off reliable and easy, very good value.
