          I was having a lot of problem with a low quality adapter. Through troubleshooting I realize the problem was the adapter and I received a recommendation to get the Keyspan USA19HS. As soon that I connected it the problem of transmitting data for a software upgrade went away immediately. Great product and easy to use with Windows 7. I recommended!

            I have one in use on a computer running 24/7.
            Each time I need to go out in the field and program another unit, I had to disconnect it and bring it along. Now I keep one in my go kit.
            The adapter has never failed me and I have read of the knock offs out there that do not always perform.
            Well pleased and although more expensive than others, you get what you pay for.

                    Tried many of these in the past with varying degrees of success. This one is the best! It does require a driver and software (included) but it is easy to setup and stays setup even after reboots and different USB locations.

                                        I use this adapter for programming many different devices. I have used multiple other USB to serial adapters that haven't communicated consistantly. This is the first adapter that works everytime on every different device I try to communicate with. It worked so well our programming group standardized on them and I purchased one for everyone on my team.

                                                I'm using this on a MacBook pro on win xp within VMware. It took installing it twice but it set up the second time.

                                                  I needed a serial port on a new Windows 7 (64bit) machine. This usb serial adapter did the job with no problems. It installed as COM3 but I needed either COM1 or COM2 due to application limitations. The instructions showed how to resolve this and make the configuration change and all worked fine.

                                                      I use an adapter continuously to connect one program with another. A different adapter dropped the comm every other day. This one is rock solid.

                                                          At first I was concerned about having to navigate a user interface each time I wanted to use my RS-232/Com-3 which by the way is missing on many new computers. In 5 minutes, I had loaded and configured Keyspan which operates in the background after config- downloaded all of my waypoints from my Garmin GPS and had the points up on GoogleEarth in a jiffy. (Used EasyGPS free download; don't forget to config EasyGPS for Com-3)

                                                            We use the product in a proprietary system to link our laptops to interface boxes. We find this adapter to be more reliable and less prone to failure, understanding the environment that we use it in.
