I bought ~15 of their cheapest 2.4ghz router to connect payment terminals ~4 years ago and it was a terrible mistake. I thought for a low bandwidth application with the router being decently close it would work fine.

Spent days trying to make it work (it would work, then lose the connection, roaming was probably an issue too) and in the end leased meraki hardware that worked fine.

I'd avoid their cheap tier of AP at least.
