Tried several different RS232/Serial adapters and they usually fail due to compatibility. These I just bought were the best and cheapest I've ever gotten. They use the PL2303 chip and work like clockwork. I use them in Arduino projects and also to create software adapters for various ham radios that I have. I use the pins that are on them for the Arduino and cut them down to fit the special connectors for the radio. I will order them again and would highly recommend them to anyone looking for a great product at a great price.
