I wish I had a hundred of these...
I bought this back in 2007 to use on my MacBook Pro for an interface to my Yaesu Ham Radio. Here we are, 10 years later, and it's still going and works awesome!

No hassle installation
I purchased a Garmin data cable for an older model etrex GPS. Unfortunately they no longer make 9 plug male receivers on computers. My customer service rep was incredible. When I plugged in my adapter it worked like a charm. Installation instructions were easy to understand and simple. I would definitely purchase from them again

I only order. I don't use the product so I can't share what I don't know.

Great Product
The USB RS-232 Serial Adapter DB-9 Male worked perfect with my female serial cable to the PC computer that only had a USB port. It read my weather station data to the weather program without any problems. The price was reasonable and delivery was reasonable that included tracking. I highly recommend this adapter if you have a female serial cable and need to go to the USB ports of any newer computer that don't have serial ports anymore.
