Review on 🐠 Aqueon QuietFlow LED PRO Aquarium Power Filters: Efficient Filtration for Any Aquarium Size from 50-250GPH by Helen Spencer

As others have said, this unit either makes noise or jams, and there are design reasons for that. into an outlet. He can knock pretty loud. If dirt or grease builds up in the impeller/axle shaft, the impeller will lock up and stop the water supply to the filter chamber. The device keeps heating up (it never shuts off automatically if the impeller is stuck). And after the impeller stops pumping water, the shaft really starts to heat up. Since the axle shaft is made of plastic, it warps. After that, the impeller will never turn in a deformed shaft again and you will have to discard the device. I bought and used two of these, brand new, from Revain. I attributed the first attack to failure. I checked out the second one. I'm sending the device to Aqueon and requesting a refund for both directly from the manufacturer. Will update as they acknowledge the obvious fact that this is a poorly designed product.
