The price to performance ratio is excellent. However, this retractable Ethernet cable will not last if you are rough with it. If it could be upgraded to reinforce the cable going into the connector itself, this would be the ultimate solution.
I've purchased many and am admittedly rough with it. I put too much flex on the connections when plugged in and have had several of these fail.
I've searched for another and found one with a jacket on the connector. So far it's good, but it is definitely not as compact or cheap as this one.
I remember getting a similar product as a freebie at a hospitality trade show about 2 decades ago and thought to myself, "man, if they only made these for ethernet!"
So when I saw these, especially on sale, I had to try them. I used one where it was stretched and twisted quite a bit and it still worked. A regular patch cable in the same application was showing a bit higher bandwidth (170 vs 160Mbps on the testing I was doing), but for the convenience of having one of these in a laptop case is second to none. The connectors on the ends are tiny and have the depth of telephone cord connectors, so you might find them a bit harder to disconnect, but that's a minor quibble that I can easily live with.
