Cheap with good quality

"What can you expect from such a low cost part?":
- Very low measurement tolerances
- Relatively stable plastic casing with no sharp Did
- No interference in four weeks continuous operation

I'm surprised really positively on the quality for such a low price. It is true that only in the first port and the USB data signal is looped through and the second port is a "port charge" is. However, the often mentioned in the reviews limitation to maximum 0.5 amps I can not confirm.

Yesterday, the second module has arrived, also with very good accuracy and cleanly processed housing.
