works great was shipped fast and packed good. Easy to hook up and get going on my 2 computers

Been a good game changer as I never thought about getting a splitter as I only have access to one port for my modem so used to have the ethernet for my console but now with the splitter I can have both my console and my PC running on ethernet without losing any speed from the cables

As of this review, this has been on for 7 months and I have not had an issue. Not sure why others have had speed issues but I've seen no lag.

Works

It has failed within 3 months of casual use. Save your money

This unit works as described provided you supply enough power from a standard USB power source. There is no mention about how much current this unit needs to operate properly. So, make sure you use a USB 5VDC adapter rated for at least 2.5amps. I've been experiencing intermittent and frustrating problems with a 5VDC / 2amps USB power supply.

So basically I have 1 Gig Fiber to my home connected to a Google/Nest WIFI Mesh system that creates a large seamless wireless network throughout my home via several WIFI Points. I wanted to convert my non-wireless printers into wireless by using one of the WIFI Points, so I connected the two printers to this SinLoon RJ45 Network Splitter on one end, and to the WIFI Point on the other end. VOILÀ! It worked instantly. Now I have taken non-wireless printers, and created a wireless local printer network. BTW - Don't forget to plug in the power supply to the splitter, because I assume it won't work as well without power.

Does what I needed...my tvs lan has a very limited throughput and this is only for consistancy since too far away from wireless router. When having that tv and my laptop connected to this my laptop still acheives over 600MB per second on A Gig speed plan.

Great product, switched to ethernet, after various issues and discovered another 500 mps to my internet speed! Currently have a 1 gb service, but my wireless hardware was capped at 300, use this for the 2 pcs in my household we regularly run 800 to to 1 gb+. What I didn't notice was that I needed to blug in the usb (provided) - fortunately I had an extra usb plug from an older charger (who doesn't), the cord is short, but any usb cord will do. I like it plugged in to the wall so its always powered up. Great product, easy to use. If you only have a single ethernet slot on your router/modem. this is a great splitter, can use both at once, NOT a switcher.

this ethernet splitter works great. so glad I found this. all the other splitters only do 100 to 300 mbs. this one can run 2 ethernet cord at the same time pushing a 1000 mbs. through both ports. great buy

Needed to get failover capability between two stacked switches in my home lab but only had a single Ethernet uplink. Now, when I reboot the “primary” switch, the second port comes up on the “secondary” switch immediately. No loss in connectivity for any of my devices anymore!

Excelente, sí funciona como switcher.

This appears to be a decent GigE (1000 Mbps) splitter that's reasonably well constructed with a typical plastic case/shell; unfortunately, it seems to have an excessive amount of retransmission errors although the speed is fairly decent during the tests. The tests were performed against another 5-port GigE switch that did NOT exhibit the same behavior so I'm forced to conclude that this particular splitter/switch is at fault and that's quite unfortunately and disappointing since I was looking forward to using it in a narrow space where this would be a perfect fit.Note that Ethernet does NOT allow splitting traffic of any sort and this is in fact a 3-port GigE (1 Gbps) switch in disguise. If you think about it, a 5-port switch would allow you to connect up to 4 devices and share the network via 1 uplink to the router or another switch and that's exactly what this splitter is (and does).A 5-port Fast Ethernet (i.e. 100 Mbps) switch is about $20 at the moment on Amazon and a 5-port GigE switch is about $23; however, both of 'em are larger than this and they are often powered by a DC/barrel connector with an AC/DC adapter (provided of course) that can be a bit of a hassle especially if it's intended to be hidden from view and/or located in a narrow space. It's powered by standard USB-C port and a USB-C/A cable is also provided, which is good.This has a dimension of roughly 6.4x6.4x2.5 cm which is relatively small/compact in comparison and I don't believe you will be able find a 5-port switch, GigE or otherwise, that' the same dimension as this and I dunno of anyone that's selling a switch that's less than 5 (or even 4) port at the moment (of course you will likely to find some odd models elsewhere if you REALLY looked).Btw, I'm not sure what controller this uses but most other 1x2 Ethernet splitter (5-port switches) that I've come across so far (about a dozen) actually use Realtek RTL8367S chip which is a 5-port GigE controller and that means there is probably a 1x4 version out there (i.e. 5 port GigE switch). If you are NOT concerned about the size or how it can be powered, then I'd say an ordinary 5-port GigE switch is a better bet and much more cost effective network 'splitter' for you. Realtek RTL8367S is used by TP-Link TL-SG105 for those who care (which I have as well).So how does this perform? Well, it's similar to most other GigE (1 Gbps) switches out there in terms of speed; however, as you can see from the results below, there are significant number of retransmissions (Retr column) which is usually indicative faulty hardware or other external factors such as interference, wiring, or even networking config. However, the same tests were performed against another 5-port switch that did not exhibit the same issue and the only variable here is this splitter. As such, this particular splitter is probably faulty which is quite disappointing to say the least.Btw, even at a100 Mbps, it's still sufficient and certainly more than adequate for streaming, 4K or otherwise since 4K contents generally use less than 25 Mbps.The following are the results from some quick speed tests for those who are interested.#### iperf3 -i10 -t 60 -c 10.10.10.12 // single threadConnecting to host 10.10.10.12, port 5201[ 5] local 10.10.10.11 port 50179 connected to 10.10.10.12 port 5201[ ID] Interval Transfer Bitrate Retr Cwnd[ 5] 0.00-10.00 sec 1.10 GBytes 946 Mbits/sec 120 1.47 MBytes[ 5] 10.00-20.00 sec 1.10 GBytes 949 Mbits/sec 202 726 KBytes[ 5] 20.00-30.00 sec 1.10 GBytes 944 Mbits/sec 44 709 KBytes[ 5] 30.00-40.00 sec 1.10 GBytes 945 Mbits/sec 221 438 KBytes[ 5] 40.00-50.00 sec 1.10 GBytes 947 Mbits/sec 55 371 KBytes[ 5] 50.00-60.00 sec 1.10 GBytes 948 Mbits/sec 44 694 KBytes- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval Transfer Bitrate Retr[ 5] 0.00-60.00 sec 6.61 GBytes 946 Mbits/sec 686 sender[ 5] 0.00-60.03 sec 6.61 GBytes 945 Mbits/sec receiver####### iperf3 -P2 -i10 -t 60 -c 10.10.10.12 // 2 concurrent threadsConnecting to host 10.10.10.12, port 5201[ 5] local 10.10.10.11 port 50310 connected to 10.10.10.12 port 5201[ 7] local 10.10.10.11 port 50311 connected to 10.10.10.12 port 5201[ ID] Interval Transfer Bitrate Retr Cwnd[ 5] 0.00-10.00 sec 572 MBytes 480 Mbits/sec 105 1.42 MBytes[ 7] 0.00-10.00 sec 562 MBytes 472 Mbits/sec 125 1.01 MBytes[SUM] 0.00-10.00 sec 1.11 GBytes 952 Mbits/sec 230- - - - - - - - - - - - - - - - - - - - - - - - -[ 5] 10.00-20.00 sec 555 MBytes 466 Mbits/sec 74 1.14 MBytes[ 7] 10.00-20.00 sec 556 MBytes 467 Mbits/sec 64 838 KBytes[SUM] 10.00-20.00 sec 1.09 GBytes 932 Mbits/sec 138- - - - - - - - - - - - - - - - - - - - - - - - -[ 5] 20.00-30.00 sec 558 MBytes 468 Mbits/sec 0 1.63 MBytes[ 7] 20.00-30.00 sec 555 MBytes 466 Mbits/sec 0 1.17 MBytes[SUM] 20.00-30.00 sec 1.09 GBytes 933 Mbits/sec 0- - - - - - - - - - - - - - - - - - - - - - - - -[ 5] 30.00-40.00 sec 564 MBytes 473 Mbits/sec 47 1.64 MBytes[ 7] 30.00-40.00 sec 562 MBytes 472 Mbits/sec 68 1.36 MBytes[SUM] 30.00-40.00 sec 1.10 GBytes 945 Mbits/sec 115- - - - - - - - - - - - - - - - - - - - - - - - -[ 5] 40.00-50.00 sec 564 MBytes 473 Mbits/sec 311 274 KBytes[ 7] 40.00-50.00 sec 564 MBytes 473 Mbits/sec 261 324 KBytes[SUM] 40.00-50.00 sec 1.10 GBytes 946 Mbits/sec 572- - - - - - - - - - - - - - - - - - - - - - - - -[ 5] 50.00-60.00 sec 564 MBytes 473 Mbits/sec 44 308 KBytes[ 7] 50.00-60.00 sec 564 MBytes 473 Mbits/sec 83 362 KBytes[SUM] 50.00-60.00 sec 1.10 GBytes 946 Mbits/sec 127- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval Transfer Bitrate Retr[ 5] 0.00-60.00 sec 3.30 GBytes 472 Mbits/sec 581 sender[ 5] 0.00-60.03 sec 3.29 GBytes 471 Mbits/sec receiver[ 7] 0.00-60.00 sec 3.28 GBytes 470 Mbits/sec 601 sender[ 7] 0.00-60.03 sec 3.28 GBytes 470 Mbits/sec receiver[SUM] 0.00-60.00 sec 6.58 GBytes 942 Mbits/sec 1182 sender[SUM] 0.00-60.03 sec 6.58 GBytes 941 Mbits/sec receiver###The bottom line is this (assuming it works for you); this is a perfectly workable 3-port switch (or 1x2 GigE splitter if you prefer to call it that) that's reasonably well-constructed and does what it claims for the most part but most importantly for me is its relatively small size and it's powered by standard USB-C which few 5-port switches are.≡ ValueAll things considered, this is a would-be decent 3-port GigE (1 Gbps) switch (aka 1x2 network splitter) that's reasonably well-built although it would've been much better if has a metal shell/case instead of a plastic one. Of course, all of this assumes it's working without issues, which isn't exactly the case for me. It's a bit pricey at $27 for what it provides and its overall build quality, versatility, and performance. Again, you can get a decent 5-port GigE switch for $23 although it's much larger than this. Your mileage might vary.
