mikrotik RB5009 is very capable router to run for hotel, or medium size office. but since mikrotik website only say its a great for merely heavy-duty homelab use, would you still use it for enterprise clients?

I mean since mikrotik not officially tell it for enterprise use.

It's a small hotel, with expected guest device capacity can fit in one /24 subnet at a time. And their hall, well more like seminar room. you get the idea. Config wise maybe 3 or 4 VLANs and QoS on traffic shaping and priority on VoIP, blocking certain ports and websites. Overall, I know RB5009 can handle.

what I'm asking for if you're in networking business, do you use consumer-grade or in this case prosumer-grade for enterprise environment knowing well it can do the job just as good? Because I heard some people insist on using enterprise grade no matter what.

I can instead choose CCR2004-16G-2S which is proper enterprise grade but seems waste of money.
