I purchased this device and after two uses, the distributor is blocked and no longer rotates. Looking more closely it seems a small plastic piece of poor quality and very fragile idles and prevents the distributor from walking. Given the quality of the elements, I can not even say that I have not had any luck so much the quality of the components of the mechanism are of poor quality. I find myself beak in the water without the possibility of buying a new machine before the holidays ... IT is better to buy more expensive a good device eheim guy I for 5 years for another aquarium and works like clockwork .... needless to say that the quality is not the same. I have read other reviews and thought naively that it was a good product, damage to me.
