Works great with my UDM-Pro and MikroTek 10GB switch. Will buy again.

Bought the 10 gig copper transceiver because I couldnt run fiber. These work fine with my Ubiquiti and Mikrotik switches and negotiate 10 gig over CAT6A no problem. They also seem well made. The only downside is they get VERY hot, like hot enough to burn you. This is not that unusual for RJ-45 SFPs, but it is kinda concerning.

Used it for a Mikrotik RB3011 router as well as a MC220L media converter (https://www.amazon.com/TP-Link-Ethernet-Converter-Supporting-MC220L/dp/B003CFATL0). Had in operation about a month now, no complaints so far. Runs at about 35 degrees celsius in my router.

I have a few Linksys managed switches and a few smart switches (similar to a managed switch with no layer 3 functions or console port). They primarily use traditional copper ethernet cables, but they each have two SFP ports for fiber. In theory these can be used for any purpose, but in practice theyre best saved for when copper cannot cut it. I use them for 30-40 meter runs in my home that get snaked through the garage and end up under baseboards. Fiber is really thin, so it can fit under the baseboard. Fiber is immune to crosstalk, so the various runs being right atop each other wont interfere. Of course another use for be extremely long runs or runs through an industrial area with loads of magnetic interference or other issues. Lastly, fiber doesnt conduct electricity, so it wont spread havoc if a connect device gets struck by lightning. Anyway, these SFP modules just plug in and work. I used Monoprice LC to LC fiber and these on both ends (in Linksys switches). Works great.

These SFPs will not autonegotiate. I have to disable negotiation which limits me to 100Mbps with some of my devices. Mikrotik switch.

When using this to uplink from a Mikrotik switch to a 2.5Gig router when trying to push upload of 1Gig or more the link would keep dropping. When the module was replaced by a Mikrotik official SFP+, problem was resolved. How ever using these to 10Gig devices they are fine. They arent stable for below 10gig link speeds.

I have used several of these in ubiquity equipment and they have worked great. No problems.

Ordered the 1.25/2.5/5/10GBase-T: 30m variant. Works in my Aruba S2500-24P switch, and negotiates 10gb/s when connected to my desktop PC that also has a 10gb/s network port. Also works in my Intel X520-SR2, after enabling unsupported SFP+ devices. Tested with Truenas Core (FreeBSD), while connected to a 1gb/s RJ45 port of the previously mentioned Aruba S2500. Yes, this particular SFP+ module negotiated down to 1000base-t (1gb/s), and seemed to function fine. The point of this test for me, is that it means I can use an Intel X520 card in my opnsense (freebsd) router, with this SFP+ module to connect to my ISPs Gigapoint 803G ONT (1gb/s RJ-45 port), and a 2nd fiber SFP+ module to feed my aruba switch / LAN.

Worked with my QNAP multi-gig switch, but not with my intel x520-da2 nic. Will be returning these.

These seem to present themselves to the switch as SR optics (SFP-10GBase-SR) which means they seem to work even in switches that explicitly dont support 10Gbase-T. Not sure if this is typical or not. I havent done any long-term testing but am very happy to be able to bring copper 10G to my relatively ancient 3750E and 3750X switches.
