RJ45 Splitter Selector Switch, 2 Ports Network Switch Splitter Selector Hub 2-in 1-Out or 1-in 2-Out 100M t 2-Way RJ45 Ethernet Network SinLoon Push Button Metal Mini Switch Box

So I bought two of these to use as kill switches. I put one on my main laptop, and one in my network closet between my modem and primary router. They work great. There are times when I'm working on sensitive documents, or doing manual mirroring between multiple computers on the same local network and I don't want Internet access during those activities. These switches handle that issue perfectly.To me, they seem solidly built, and in fact out of curiosity I pulled the back off of one and it appears to be well designed and manufactured. No extraneous wires, everything is on a printed circuit board with good clean solder joints. I also ran an Internet speed test and there was zero change from what it normally would be without the switches in place.Hopefully the longevity is there, but they seem like a great deal for the price and quality.

It’s doing a great job and for the price you pay, it’s a great bargain!

I'm using this switch to change between 2 internet services, works great.

It makes a cool click when you switch A to B and back. No internet signal loss, was easy to install.

This is a simple option to connect two devices on the same line for the modem but only one can be used at the time.Example if you are a gamer and have two devices and only one Ethernet cord in the room then this allows to switch the line between devices with the push of a button, instead of unplugging and plugging in the cord between devices on the daily.This switch is a good value, feels cheap but that is because it's cheap. The kids are using them so got a couple under stress testing and so far so good. Will revisit this if something goes bad.Recommend it and would buy again

Perfect product.Seems to be made well.Excellent for my needs.

No on/off label or indication. This is not first-rate, but it works.

I am very pleased with the purchase. This removed the need to constantly plug and unplug an ethernet cable between two machines. Now I just push a button when I am using one machine or the other. My only complaint is that the markings on the device for the A & B ports and buttons are hard to read from far away, but I resolved this by printing and attachings labels next to the ports and buttons.
