Es un muy buen sensor bastante preciso y exacto, claro tiene sus pequeñas variaciones pero obtienes un sensor de buena calidad a un buen precio, claro si usas un buen codigo, les paso de consejo que de preferencia alimentenlo directamente de arduino y si van a usar otras cargas (displays o algun otro sensor) hagan otro circuito externo para alimentar esas cargas, ya que si no, les va a dar bastantes errores en la medicion, lo digo por experiencia, y no es error del sensor, sino que como el sensor necesita 5V de alimentacion, cualquier variacion de voltaje sera proprcional a la medicion.

I quickly found a bunch of resources for using this in both AC and DC circuits. Measuring the current in AC circuits requires a sinusoidal calibration program/library due to the behavior inherent to AC. These resources aren't too hard to find. In this two pack, one worked and the other was DOA. So if you need both, buy a couple or find a higher quality vender.

Works great, I've so far had no issues with it and it's output matches my multimeter's output.
