I purchased a UF-RJ45-1G SFP module to use in a US-8-150W, works fine, plug and play. Just keep in mind that this module is 1G *ONLY*. If your device at the other end isn't 1G, then you won't be able to make a connection and you'll be confused as to why it isn't working. Didn't even have to reboot, just plugged in, was immediately available, can be configured with Unifi management software.Be careful of cables with large "boots". I had to trim one back to get the plug in all the way to the socket. Also note how the module locks in when inserted, you need to unlatch the gold clip at the front to remove it, else you will break the socket in the switch.

Setup dual WAN on my UDM Pro and needed to convert one of the SFP+ ports to RJ45. Plugged in and work perfectly.

Bought 4 of these for Unifi switches (US-24 and US-24-250W). All 4 worked without a hitch.2 of them served to trunk between the switch, 1 as a uplink to the router and 1 as dedicated link to a home server.A few things I want to point out1. They do work as an extra network port, though they won't be auto-negotiating.2. NONE of them heat up.3. Getting them out does need a bit of finesse. A testpen works great.4. I did a simple throughput test from the server through switch 1, switch 2, Google wifi and out through fibre broadband (subscribed 1gbps link) and hit close to 800mbps down and 900mbps up. Guess they are switching alright.Best bang for buck network gear I have bought.

Update 11/28/2018Replacement arrived fast and worked right out the box. Got give them a 5-Star for excellent customer service and for standing behind their product.Company even refunded return shipping cost for their defective module. This is what all company should do and by far hardly none of them do this. This kind of service will keep me as a loyal customer to 10Gtek.*********************************************************Update 11/20/2018:Company reached out to me for warranty support. Extremely happy with this process of them reaching out to their customers and assistance with warranty process. Definitely surprised on how fast and customer oriented they are. Working with them on a return and will upgrade this back to a 5-Star in the meantime. Will update regarding new module when it arrives.*************************************************Original Review:Came in and they worked like a charm. Fast forward 2 months later and one already stopped working. I’ll have to check about warranty on these things as anything connected to the one module isn’t communicating properly.

Rock solid for just shy of 3 years when it failed. Failure most likely caused by EMP (traveling down a long ethernet cable running into the attic) from lightning strike nearby which caused this item and a connected smart switch to fail. Just guessing on the reason for the failure - but what is most important is how quickly and painlessly this vendor honored the warranty and replaced the item. Plug it in and it works - enough said.
