Yo lo uso para proyectos donde manejo 2 baterías AA (3v) y tengo una salida buena de 5v, hasta el momento me a funcionado bien para proyectos basicos y no he tenido problema, para proyectos donde no requieres el USB es un poco difícil quitar el conector

The price-performance ratio for this converter is very good! They work well, if not too much damage to the ferrites of the coils are present. Because half of our delivery had more or less broken ferrites at the inductances. This of course can have influence on the efficiency. We will send a photo.
