A very useful cable
The drivers are very easy to install and the actual cable is made to be rugged. The instructions are very simple and the price is affordable. It also has a high data transfer rate

Solid USB-2-Serial
Solid cable structure which will lend to a long life for the converter. Unit works completely as advertised.

Tried One, Bought Five
If you purchase the cute blue USB to RS-232 adapters from China, you will be sorry sooner or later. They don't even come close to meeting the RS-232 spec, using zero volts as a cheap substitute for the minus 3 to minus 15 volts specified for the "mark" voltage. My radio demo was going down in flames until I changed to a Tripp-Lite U209000R that provided a "mark" voltage of minus 8, right in the middle of the specification values. I'll never go for "cheap" again.

I definitely recommend this product
I use this product to connect to our color inspection cameras for the automotive industry. These cables last. Other brands don't hold up like this one does. Great product!
