5 Ports 2.5GB Ethernet Switch Unmanaged Network Switch | 5 x 2.5 Gigabit | 1 x 10G SFP+ | Multi-Giging Switch Works at 10-100-1000Mbps | 45G Bandwidth | Plug and Play | Fanless Quiet Metal Internet

No issues with these. I haven't tried the SFP connection with optical. It would be ideal for daisychain more than one of these together. It does connect at 2.5Gbps and gives the rated speed. I didn't feel any heat concerns with it. Just plug and play. Your modem/router needs to support 2.5Gbps and ISP to support 2Gbps speeds or faster to see the results on speedtest with a 2Gbps plan for faster. Home use device to device on LAN you should see about 220MB a second file transfers depending on your device capabilities.

This switch works as intended. Nothing fancy or special about it—it just does the job it’s meant for. Plug it in, connect your cables, and it works without any issues. Solid and reliable for basic network expansion.

It does work, and is very cheap. You're not going to get the absolute maximum possible performance compared to a quality name brand switch that costs twice as much, but if you don't care about squeezing every last ounce of performance, this switch should do fine.

Simple plug-n-play switch to connect multiple 2.5G devices to your network. Plugs into a standard electrical outlet for power, via a plug adapter, and provides 5 2.5Gb ports (1 in and 4 out), plus one 10Gb SFP port. It's quiet and small enough to place almost anywhere. Accepts standard RJ-45 network cables, which should be CAT 6 or above for full speed transfer.

Needed a switch for 2.5Gb NAS transfer speeds. This works great. Love how cheap it is. The only thing I didn't like was that the wall mount holes did not have much clearance for screws/nails with large heads. The heads have to be really flat to fit. I had to visit a hardware store to find something that would fit.
