Looking to add nanoswitch outdoor 4 port poe will this work?

Hello I have a very interesting setup and looking to see if I can use this $35 switch instead of the say $100 one for my current deployment.

Link to item: Ubiquiti NanoSwitch Outdoor 4-Port PoE Passthrough Switch (N-SW) https://www.amazon.com/dp/B079SPW2QL/

I currently have two locations, A and B.

A has the modem and Netgear router with wireless disabled and just being used as dhcp for the UniFi system and a switch. One port is plugged into a Poe injector connected to a nano beam ac gen2 which connects to location B. There is also another netgear switch that is being used as an unmanaged switch and connects a single computer and a UniFi UAP-AC-PRO.

Location B is connected from a Nanobeam ac gen2 to a Poe injector with lan connecting to a netgear switch unmanaged. I than have a UniFi controller connected to the switch and a Poe injector to a UAP-AC-PRO.

Here is my thoughts: buy 3 of the nanoswitches and place one at location A to replace the netgear switch connecting everything and enable dhcp directly from the modem, also moving the cloud key to this. Than replace the other netgear unmanaged switch and connect the first nanoswitch to it and connect the AC Pro and computer to that switch. Lastly replace the netgear unmanaged switch at location B.

Does this make sense? I can’t see why this wouldn’t work but wanted to verify. Would I have any issues with multiple Poe devices connected to it? Would a non Poe computer have an issue if all it’s doing is acting as a unmanaged switch?
