BOYU CJY-1000 Aquarium Air Pump Work Smoothly Silent 1L/Min 1.7W
A part of the review has been auto-translated.
1) Model CJY-1000 does not have air flow controller! 2) low noise
Es fantástico, es el mismo que encuentras en las tiendas especializadas de tu zona pero mucho mas barato. En las fotos engaña, este modelo no puede regular la potencia de salida del aire, el ruido esta muy bien.
appena arrivato e montato è estremamente silenzioso arriva con presa cinese e con adattatore leggermente difettoso l'ho sistemato con un cacciavite. l'aria che fuoriesce è sufficiente per il mio acquario da 25L
The plug transformer is wrong, this way the device unusable in Europe (look at my uploaded pictures). The bigger problem is that on my device (CJY-1000) the air flow controller is missing (look at the uploaded pictures). Please send me a device which works exactly as described in the advertisement!
