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.

    It's hard to find this type of the cable these days. Although this is a short one, but I still can use it for connecting the computers.

    Doesn’t require a separate serial cable like some other adapters, so as long as youre okay with it being relatively short, it works perfectly. I have it connected to an old analog switch device that uses rs232 for control and it didn’t have any issues.

    I needed this adapter to configure equipment at my work. It worked great. No issues at all. The cable can be purchased on line for a fraction of the price but I could not wait for shipping. Having to pay the higher price is why I gave 4 stars other then that it is 5 stars.

    I purchased this to connect to the console port of a firewall. It worked fine for my purposes, but since I purchased an open box version the pins were slightly bent when I received it so I had to nudge them straight before I could use it. I would have given 4 stars regardless just because these are a a dime a dozen and there isn’t anything that particularly stands out about this one to warrant a 5 star review.

    The insignia USB to Serial connection worked really well as long as you know how to change the port in Device manager to match what peripheral and software requires you to use. Very simple in nature without bulky software needs. just what i needed for my it work
