Review on DTOL Type Female Male Adapter by William Chavez

As several others have written here, this is a useless article. There is no mention of a right of return until purchase. Mine was dead on arrival. It's such a simple device - just four wires to convert between two different four pin USB ports. I checked mine with a multimeter after it didn't work on 2 different devices. Only three of the four pins had continuity between the two sides, and two on one side connected to a pin on the second side! After complaining to Revain and getting a refund, I decided to take it apart. I found several problems. Two wires touched on one side where the solder insulation had been removed. This caused the 2-to-1 continuity I discovered. The four solder joints were cold soldered, so there was poor or no electrical contact between the wire and the connector. And finally, a wire was pulled out of the cold solder joint as the wires were twisted to fit the plastic case. Overall very poor production, even for a $5 part. Unfortunately, mine is going to landfill soon.
