Customers are saying

Customers have good things to say about the USB to serial functionality, compatibility with various operating systems and devices, and the ease of use of this adapter cable. Many appreciate its quality and durable construction. However, some customers point out that the cable length is short, and that the lack of included drivers may pose a challenge for some users. Overall, the positive feedback on functionality and ease of use outweighs the concerns about cable length and driver support.

    Our department was having trouble getting this cable. Many were counterfeit (being labeled as Prolific, but not infact Prolific). We went with the Best Buy name brand cord as a safe option, and have not been disappointed

    Works exactly as advertised. This is a good quality cable and was kept in stock at my local Best Buy. My girlfriend needed it urgently to replace the old one for her Stenograph machine, and we are very happy with the results. Keep in mind that the length is quite short, so make sure to get the appropriate length for your needs.

    I bought this thinking I needed to use it to access a kernel crash dump; when hooking up a KVM switch to a running system, the newly connected USB ports are not recognized on a VMware ESX server, so the server has to be rebooted to establish connection. You can't login to the server and issue a command to rescan the ports because it is hung in a kernel crash dump. The cable was too short to be able to be used for this application; I could have bought or found an extender cable, but my manager didn't want me touching the systems because they were being used for long running tests, so I returned the adapter. I didn't get a chance to see if it would have had a live connection to the crash dump.

    Needed to connect some legacy equipment to a newer PC. I was shocked that BB had these in stock in a local store when everyone else that sells them wants to ship it. Worked flawlessly. No installation of external drivers needed, Windows 10 did it all. Perfect solution.
