    I bought a few of these to daisy chain a few CAT5 cables together to get wired signal to my attic for my PS4; they work perfect. No problems.

    Don’t waste your money. If it seems too good to be true it is. Inconsistent performance and poor Speedtest results from using this across multiple cables, Mac/PC, etc.

    I had two cables. Neither one was long enough to do the job required. I joined them with this, now it is like having one cable.

    Not much to say, this either works or it dosn't. It did what I wanted it to do. I was in need and was able to find it stocked at my local store. Depending on your need, you can get similar product on line for half the price that will work just as well.

    As with most insignia stuff it’s not very well made, and it’s too expensive, but it serves the intended purpose in a pinch.

    The home where I live doesn't have the best Wi-Fi reception… So in certain rooms I needed a hardline. However I was just several feet short to the office room desk adopter worked out just great!
