Arrived quickly, packaging is simply great. Unfortunately it is not soldered very well and the single port connection side was already worn out (insulation). The connection to my computer was definitely unstable, but I can't say it's 100% wired because I'm using someone else's computer. I can't say 100% that the ethernet port on a borrowed laptop is perfect. I was not aware of any problems with the computer and did not see any possible physical damage that could cause the ethernet port on the computer to not function properly. Unfortunately, if the insulation hadn't been frayed upon arrival and the cable had looked better, I wouldn't have had reason to feel this way. Unfortunately, this one appears to be "bundled together" and not properly tested with any sort of quality control. People use them for coding and diagnostics that require constant connection without the possibility of modules failing and requiring much deeper repairs. Don't buy from them again, I'm on a lower income and can't afford another one so I have to use this one. But if I had the money to order a new one. I don't think after this experience I could trust the company to send me something well designed. sucks. I hate leaving bad reviews.
