> 3 dayBought 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.

> 3 dayI connected the module to a mikrotik CSS610, with the other side on an Asus Z690 MB that supports 2.5GBE. With no additional configuration, both sides auto-negotiated at 2.5G.

> 3 dayThese 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.

> 3 dayBought this as a much less expensive (by 40%) alternative to the highly rated 10Gtek SFP+ to RJ45 10GBase-T adapter. Its been working just fine in the SFP+ port of a D-Link DGS-1510-28X to provide the 10G link to a ReadyNAS 626. Throughput is as good as Im able to test with mostly 1G equipment. Heat generation doesnt seem to be an issue so far, although it is definitely warm to the touch. Packaging is fairly plain, but Id rather pay less than get a fancy box to throw away.

> 3 dayI bought two 1Gb SFP+ one works the other does not detect link. Changed cables etc, no luck, Asked for a refund/return but since is international order is more expemsive to return than the price for a quality one. Will not buy this brand again.

Greater than one weekWorked to add another port on a QNAP TS431XeU. I dont have a 10GB switch so its currently working at the 1GB speed.
