Rated 5 out of 5 byWoody from Communicates Successfully Every TimeI have hundreds of clients who have equipment with which I occasionally I have to communicate. I use an Apple laptop with the latest OS. Because the client's devices use only PC Windows, I use Parallels to convert to the Windows platform. Then I use the Keyspan serial adapter and a special modem to get the signal onto the phone lines. The Keyspan works every time.

Rated 5 out of 5 byDanielRich from Works reliablyI've used other USB -> Serial adapters, but I never have to wonder whether my Keyspan will work. This is the second one I've owned, since a customer of ours wanted the first one. I had no problem recommending the Keyspan for his application. I keep one in my computer bag.

Rated 5 out of 5 byRob Dunn from nullIf you configure network gear and you are using a somewhat slimmed-down laptop/ultrabook, then you absolutely need one of these. If you have a USB port, you can plug this in and use something like Putty or TeraTerm to connect to your network devices for serial configuration. An absolute must-have for any network admin worth his salt.

Rated 5 out of 5 bySplitInfinity from One of the most reliable USB to Serial adapters we've seen...I buy these for our techs 5-10 at a time. We've tried a few other USB to Serial adapters, all of which we had issues with. Not the smallest, but these have been rock solid, work every time. The software makes it easy for the user to see what Com port the device is using. The connector is a USB A connector held in by friction, and won't take too much cable weight, but if not put under strain stays in fine - if you swing it around a server room a lot you could add heat shrink, cable ties, or a rubber band to make sure it stays in tight. We've had fewer issues supporting our techs with these than any other adapter. We have over 100 mobile techs around the country and world using them to program routers, or load firmware in various types of devices...

Rated 5 out of 5 byjosh13 from Easy to use, great software interfaceI use this adaptor for interfacing with several devices, such as a range of servo drives, which don't interface with other adaptors easily. This is very easy to set up, the software allows me to change the ports quickly and easily, and it works with everything I need it to.

Rated 5 out of 5 byRetired Apple SW Engineer from Best USB / Serial Adapter Out ThereContrary to other posted comments, this device does work with El Capitan. I have two that are on two different computers (an iMac and a MacBook Pro) that receive daily use. About to purchase a third for a relative to use on a Mac Mini. I've deployed these on several Windows systems too. Absolutely 100% reliable and works without a hitch on both Mac OS X and Windows.

Rated 5 out of 5 byBombastic, LLC from AV Industry must haveA lot of legacy and even current AV equipment still uses serial cable communication. I have a MacBook Pro running Yosemite, with Windows 8.1 running in Parallels. MOST of the AV configuration software is Windows only. This device allows my Virtual Windows PC to talk to an external serial device with this adaptor as if it were all native on it's own machine. Fantastic!

Rated 5 out of 5 byUncle Terry from Rock solid compatablity.I use the 19HS and the 49WG (4 port) with my ham radio gear. I have never had any type of issue where the software did not recognize the adapter as a native serial port. I went through about a half dozen other brands giving me some sort of problem before I found this adapter. The software is also in a class of it's own. I will not buy nor recommend anything else.

Rated 5 out of 5 byCazi from nullWith laptops these days not coming with a physical serial port (understandable as they get thinner and thinner) a USB to serial adapter is needed. This adapter works pretty well. The only thing that is sometimes annoying is having to look up which com port it was issued in device manager before being able to use it with PuTTY.
