Still pricing is insane. That is a dumb unmanaged layer 2 switch, and they want $330-350 for it. I get that is "cheaper" than others for 10gigabit capable NBase-T ports, but that is still $70 a port for unmanaged ports.
If I was going to spend that much money, I would much rather pickup a used/refurb Brocade ICX6450 off ebay for around $150 and buy 4xSFP+ NGbase-T transceivers for another $200 (that is assuming I need the ports to all be RJ45 ports, and don't have or can't buy SFP+ based network card for one or more systems and use cheap twinax cables to connect to it, saving the cost of needing the transceiver and probably another $30-50 on the network card). For approx the same cost, I would have a layer 4 managed switch, with 48x1gb ports, and 4x10gb capable ports, with support for VLANs, ACLs, and port aggregation/bonding. Sure, I give up 1 10gigabit port, but at least with this switch you can setup proper network segregation for a guest VLAN, or one for IoT devices.
