Fast shipping, product exactly as described. I have an aquarium of cichlids, African cichlids to be precise, they love to dig and change decor fairly regularly. I once found a pile of sand over the filter inlet that always made an odd grinding noise no matter how often and/or how detailed I cleaned each component. I have two Emperor 400s on a 120g tank, one was quiet and the other annoyingly loud. I noticed that there was large engravings on the noisy side propeller and very little toast on the magnet side. I doubt it would be perfect and all the noise would go away, you said hello what time is it 8pm. This was the best money I've spent, not only did they work, they are completely silent, and most importantly, my tank is super clean, I'll post a photo.
