It will work for now....but receiving can be fussy.
I'm using a laptop with Windows 8.1 on it and using it to control an RS-232 controlled receiver. Upon turn on I can command the radio immediately, however, I have to pull up the original control program and reset everything to get data from the receiver to go back to my laptop (confirmation data, S-meter data, etc.,)

Requires Driver Download
I bought this device because of the activity lights that tell you that you are connected. A great feature to have when troubleshooting devices that are reacting slowly to terminal input. I was a little disappointed that there were no default drivers in Windows 7. This device requires a software download and installation before first use. This is the first time I've had to do that with a USB serial adapter. However the driver software was easy to find from the manufacturer's website.

Best version I've found with the built in Diagnostic LED's
Works perfectly, although you may have to hunt down and install the correct driver to make it work properly on a Windows 10 machine. The LED's are a nice extra so if you aren't connecting, you can verify it isn't the RS-232 hardware that is failing and can help troubleshoot what the problem actually is.

Decent rs232 to USB solution.
Purchased for use with PLC's and peripheral hardware. Comm lights are quite useful. Presentation is a bit over the top. I used this sucessfully to go online with a SCR drive that required a null modem connection. I had to use a gender changer style null modem adapter, which worked perfectly. Strangely enough when I tried to pair a standard null modem cable, I wasn't able to get comms (as indicated by the pilot lights on the unit). I look forward to thoroughly testing this cable on legacy serial based hardware.

Good serial cable with high-state indicator with decent length cable
not a bad design, but it could use a few options.. the LEDs are on for high, off for low, so you don't see which signals are actually being supplied. my old loopback tester has red for high, green for low, off for no signal, which is a much better indication.. installed very easily, but I have 2 other USB serial cables I use.. For anyone using these for programming ICs or certain areas, go into advanced settings under devices and change the latency to 4ms. 16ms (default) can be way too long to be recognized correctly in many devices (BetaBrite/Alpha message signs, even laplinks between computers, amateur radio tran/receivers)

Finally, a solution for modern computers needing a serial port!
Works on my laptop with Windows 10, perfectly. Other dongles with the Prolific chipsets (2303 or otherwise) all were extremely problematic and would either fail to register as a COM port or would potentially crash the computer, altogether. This isn't just a "Windows issue" because I have other co-workers who need COM ports and own Macs, and the Prolific was a pain with them as well. This adapter, however, worked out of the box with no additional drivers and I have yet to have any issues with it.

Highly recommended
As a Network Engineer working with Cisco products it is necessary for me to have a serial port available to console into routers and switches and new notebooks no longer have a serial port as a standard feature so USB serial adapters are required. If you just have a cable then if the console port does not come up then you have to figure out if it is the notebook or the console port that is causing the issue. Having the LED breakout indicators makes this much easier. I highly recommend this product.

Status LEDs are very useful
The combination of the FTDI controller which is solid and ubiquitous (you likely already have the driver loaded) and the status LEDs for each signal line make this a great debugging tool. The blue power LED is a bit too bright (aren't they always) but it does make it easy to tell if the device is connected. The materials aren't fancy but feel solid and the cable is seems rugged enough. This one costs a bit more but if you think you might want to see what's going on with your serial comms then this one is worth it.

Visual Datasets
This is about the BEST USB Serial Adaptor I've used so far. Working in the telecom industry we've had a number of these units over the years as most laptops no longer have a serial port on them.
The biggest benefit is being able to see the datasets on the physical side. Visually identifying transmit and receive can save a tremendous amount of guess work on determining which direction to look when isolating problems. Is it the device, laptop or the adaptor?

With visual indicators confirming the physical connections is priceless.

Works great, no issues with Windows 10
Works great, no issues with Windows 10. I'm happy. One nit I will pick though is that the sticker with the LED indicator labels was installed in a somewhat misaligned position so if you're looking at the device form the wrong angle you could mistakenly believe that the wrong indicators are illuminated... I started peeling up the label to shift it back over to where it's supposed to be but the adhesive wouldn't have been good for a 2nd application so it's staying where it is.

I tried installing Windows 10 and my prior Prolific usb to serial adapter did not work with Windows 10. I actually often had trouble with it working in Windows 7 after each update too as the drivers were constantly prone to errors. Apparently the makers of those devices have abandoned them. As far as this GearMo USB RS-232 Serial Adapter goes, I can confirm that it is plug and play with Windows 10. I first installed it on Windows 7 prior to the upgrade (simply plugged the usb in and Windows found the proper drivers). I then went into device manager and changed the com port and baud rate in device manager to the proper com port and baud rate. I then did the Windows 10 upgrade. After the Windows 10 upgrade I just needed to go back into device manager and update the driver. Boom, works now perfectly. I can only assume that it would also be plug and play with Windows 10 if you simply plug it in and Windows will find the drivers. But anyway, I am using this now on Windows 10. I am a very happy camper. I had years of frustration with the Prolific usb driver and am so happy to be with GearMo FTDI chip technology. Thank you so much GearMo!!!!!

Worked as expected. Indicator lights are really helpful to know things are working. Easy to load driver from CD. I used it with Windows XP.

I purchased this cable adapter in Nov 2014 and started using it in Jan 2015. While it took a bit to get the drivers loaded onto my tablet, once I managed it, the cable worked fine. At least until July 2015 when it went completely dead. Fortunately, I had purchased another cable from a different vendor (Valley Enterprises USB to RS232 Serial DB9 Cable Adapter FTDI Chipset) so could continue working. We'll see if this cable will last more than a measly 6 months!

As a side note. I had to download FTDI drivers from online to make these cables work with some of my equipment, but for other it worked fine with the supplied drivers. http://www.ftdichip.com/FTDrivers.htm

FTDI worked where others would not.
The traffic lights are a nice touch since I work on some old flaky equipment that locks up when you are programming it. Tried two others before this one and yea the FTDI chip is the only major difference. This one has the FTDI and it worked where others would not.

Blue plastic is medium grade and feels like it will break with rough use. I work in the field and it will be used roughly.

Even though the plastic is not the most durable and feels like it will break I give it five stars because for the price it is not an issue to have a spare or two on hand.

A great USB to RS-232 interface that does what it should.
Ordered this to interface my amateur radio to my computer. Initially I have tried to use other brands of interfaces to hook up the RS-232 interface on my radio to my computer and always seemed to have some glitches. Since most if not all computers have now decided to remove the serial interface from their systems, it has become more difficult to interface some of the radios that still rely on the RS-232 interface. This unit fills the bill. I plugged it in to my windows 7 system and it immediately started loading the necessary drivers. I was hooked up and communicating in just a few minutes. It also has handshake indicator lights in case a problem arises. All in all a first class unit that does the job quickly and effectively.

This serial/usb adapter came with a driver disc and has worked well right out of the package. I am using windows 7. I don't have to plug in and reboot for this adapter to be recognized. Just plug it in and go. The driver allows you to select the com port I want as well as many other settings. Much better than the last one I had. I would buy it again and recommend for anyone with serial data needs with only a usb port on a laptop or other computer to use. Finally, a serial adapter that really works!

Finally, one that works!
This is a high-quality and highly functioning adapter. That being said, the included drivers were ridiculous (Win 98, Win CE, 2000, XP, and that's it... what, no Windows Bob?) but they worked with Windows 7 just fine anyhoo. After 3 failed attempts with other "reputable name" USB-to-RS232 adapters, I'm finally able to get my MicroLogix 1000 PLCs talking to my laptops. The key was to eliminate the Prolific brand chipset from the equation and bring on the high quality FTDI chipset this adapter sports. The serial line signal activity LEDs are a plus.

I highly recommend this adapter!

Shows up without a driver install under Windows 7 and Windows 98 SE under VMWare. Beautiful.

The length of the USB cable makes it easy to plug straight into whatever machine you're hooking up to, but because it has the thumbscrew sockets on it, and whatever you're plugging into will as well, it's impossible to use without an extension cable. I opened mine up and removed the sockets. It's uglier now, but more useful for me.

Very reliable, genuine FTDI chipset, RS-232 converter.
I've used this RS-232 Serial converter for connecting to Cisco networking devices and various other networking equipment that utilizes a console port. This device was able to connect to all of them flawlessly. It was able to auto-detect the baud rate to apply for the connection and whether or not flow control was needed, which was reflected on the LEDs for each device connection. I also used this cable to xmodem a IOS file to an old Cisco Catalyst 2960 switch. This is a genuine FTDI chipset used in this device, http://hackaday.com/2014/10/22/watch-that-windows-update-ftdi-drivers-are-killing-fake-chips/ this link listed the drivers that affect fake FTDI chips. I updated my adapter to use the latest version that would "brick" the device and it is still detected and functions perfectly. I also made use of this adapter in linux using putty and cutecom and it detects perfectly as well, no need to modprobe usbserial vendor=0x???? product=0x???? it is plug and play.

I've been running this thing continuasly for about a month interfacing my weather station to a computer and have had flawless operation. The Prolific version constantly crashed on Win7 home and pro. As a former IT Manager I thought that I could make the old one work, but the problem was the driver and no version I could find would fix it in Windows. I've used it with Linux, but this unit was the only thing I've found that works well with Windows.
