For this much money I'd expect some quality. I live next to the ocean, and the pot metal connectors on the 12V side rusted out so much I had to cut that end off and hard wire it with the voltage reducing resistor to my power supply, then hot glue it to seal out the salt air. If that's the way I wanted it, I would have just bought a 30 cent resistor and used a spare USB cord and made my own power cord.
