I bought this to configure older UPS NIC cards that need a 9 pin connection which my laptop does not have. With this I can plug in the adapter to my USB port and get my work done.

I have two of these. I plug them in and they just work. I have a computer hooked up to my firewall's console port just in case I need to communicate with it in that manner. The other one I keep in my tool bag in case there is other network equipment I need to hook up to. Preliminary build of some networking equipment this would be invaluable for. There are still times you need a COM port. It's nice to be able to simply add it to a more modern computer. it has onboard lights so you can see activity. Really a nice device and never had problems with it.

I needed the USB to serial for both a Windows and MAC, fortunately it worked on both systems without a problem, however, if I had needed to install any software on my Macbook I would have had a problem. The mini CD with the software cannot be loaded in via a Slot CD reader.Consider sending a full size CD in future that will work with all readers.

I struggled with this usb serial adapter for hours with Windows 10. Used the included disc with drivers. Never could get it to work. However, with windows 7, it was easy. Plug and play took 10-15 minutes. Did not need driver disc. Then it worked like a charm. I was able to download and install new firmware for my ioptron telescope mount.

I was looking for an adapter with a win 10 compatible chip
The web site descriptions were not totally convincing so I called to verify and was on the phone with Rene who had the expertise and understood my questions and promptly answered them.

Perfect all in one USB adapter for multiple OS. Great pricing and value. This was recommended by a coworker located in the UK who is a software engineer. He tested many, and this one stood out above the rest! I now recommend this to my customers to ensure they have a great product that is reliable!

I installed the new USB to Serial adapter in my laptop and got it working quickly. My old Prolific adapter wouldn't work with my Win 10 laptop, but this one works very well.

I liked that Windows 10 recognized it instantly and loaded drivers for it, the disc was not necessary. This adapter is mechanically exactly the same as the COM connector that is found on the XP and older computers. I plugged my radio programming cable into it and the computer found it in 2 seconds. Communication to and from the radio was faultless. I don't know why other reviewers are complaining about the female threaded studs, perhaps they don't know what a proper COM jack is supposed to look like? I did notice some other devices similar to this one that have the correct male pins but have the hold down bolts of a female plug instead of the nuts found on a jack, but those by definition are not standard COM jacks, but are instead a mechanical corruption of the original concept. I find nothing to dislike with this device other than perhaps it could use a bit longer wire.

The RS-232 adapter shipped promptly. It was plug and play with Windows 10 Pro 64 bit. It works well with some very demanding software.

I have to use adaptor for work, and it works great. No more problems, no more worries that my laptop will crash in very critical moments at work. Absolutely grateful that this adaptor was suggested.

Works with all my laptops connected to various control units, door access systems and modems.
By: Ron on 2015-08-18
Well packaged, nice looking. These work well from what we have seen, and are reasonably priced. They come with a software disk, and a brief owner's manual.

This unit works far more reliably in far more conditions than any other unit I've tested, which is a lot. Agree that the cord pulling out of the blue plastic is the only real issue.
By: Chris on 2015-07-18
So far product is working as advertised. No bugs or glitches yet. Operating on Windows 8.

Timely delivery. Works fine.....

We have bought several if these adapters because they are compatible with our hard to please devices. We have tried other devices from Belkin and others and This one ALWAYS works.
There are two LEDs that show action on the RX and TX lines which is helpful.
The only downside that we have ever seen is that the cable can fall out of the blue part a little. We are rough with these and the get dragged in and out of cars. They naturally get caught and tangled on just about anything so I wouldn't say the product lacks.

Very good product. It works as advertized. Good vendor. A good value for a low price. I would buy again.

...when I just plugged it in, no disk, and it was picked up right away by my Vista 32-bit Home Premium laptop. We'll see what happens as time goes on.......

A very useful device. Incredibly tolerant of everything I have subjected it to. Worked flawlessly with the drivers included (on a 7cm CDROM) on Windows XP and XP Pro. Ubuntu recognized it with native drivers. Works with arbitrary baud rates correctly under Windows but Linux takes a bit more work. On Ubuntu it does work correctly with standard 16550 UART speeds right out of the box.
Neatly assembled and sturdy for its size. Good quality receptacles on both ends (USB and DB9).
Recommended for the price.
