Rated 1 out of 5 by from Now useless with windows 7/10 64bit I have this cable for a really long time. It used to work fine but as new driver updates were released, it started to get less and less support for my need. I used to utilize this adapter to program radios, home automation devices and many other utilities like reverse engineer rs232 protocols but now it is useless.Some of my software do seem to work only one way (transmit PC to device but from device to PC, no response). Some other sofware does not even connect and only 2 out of 8 software/utilities I use work now with this cable. Even though the driver are windows 10 certified, that thing does NOT work.If you plan to use this for speciality products, DO NOT buy this adapter.The ONLY way have been able to make this cable work under windows 7/10 is to install an old 2008 driver v3.3.2.102. With THAT driver, absolutely no issue, it works like a charm. This is the ONLY driver that works with ALL my programs.If you have difficulties like me with speciality products, you absolutely need to try the driver v3.3.2.102, I am pretty sure it WILL work but as new driver will be release, windows always find a way to update it even if I have put the ID product NOT to upgrade.So each time I get a window update, the driver gets override EVEN though I said windows NOT to upgrade this particular device. Construction of product is OK. Was worth it when it did work but now with no response from anybody I try to send this information, I get no support back, it is useless even though the electronics inside are still good. Driver issue.

Rated 5 out of 5 by from Excellent choice for a modern laptop with no RS-232. We frequently need to connect to a wide variety of equipment via an RS-232 console connection from a laptop. While older laptops often had such interfaces, most current models do not. This handy device does the trick. So long as you've installed the driver before plugging it in, the experience is flawless.

Rated 5 out of 5 by from Awesome! Needed a USB to Serial. Back in the day this was such a pain. However, this cable works like a charm on Windows 10. My old Dell Laptop can finally RIP.

Rated 4 out of 5 by from These guys are great. We bought all of our Mini-HDMI to DVI cables through them for our Intel NUC desktops. Great cables without the need for adapters.
