4Pcs DC 3-5V Micro Submersible Mini Water Pump with 2pcs Clear Vinyl Tubing Flexible PVC Tubing(1M) for Aquariums Fish Tank Pond Fountain Hydroponics Garden(4PCS Black+Tube)

The first pump didn't last a couple hours, haven't tried another yet, because it's more work than the pump is worth.

I bought these October 2023 and didn’t start using them until the beginning of February 2024. I place a sponge filter over the pump to prevent small debris from entering the pump and placed in a tub of live aquatic plants for circulation. It is now March. Two of the three pumps have stopped working and the third started whining in the middle of the night last week. So I don’t anticipate it will last much longer. Even with the filter to prevent any crud from getting in and damaging the pumps, they still stopped working in a very, very short time. What a waste!

These work wonderfully. One of my friends I bought me a well and the pump did not quite work as well and it ran on batteries. I was able to replace the oat pump and remove everything that required batteries and put this in there. It’s a wonderful purchase and very relaxing.

I was using this to circulate water in a couple gallon shrimp tank and the flow was so strong I had to modify the pump so there wasn't a constant whirlpool. I tried one in a 10 gallon tank as well and was still far too powerful. They work fine for their purpose after some modifications but they are the loudest pump/ filter i have ever owned.

Loved the size of the pumps and the flow was what I was looking for but all 3 pumps died within 2 weeks. They were also noisy but it didn't bother me that much.

These little pumps work pretty well!- They're not super powerful- They're not super quiet- They're not super durableBut most importantly....- They're not super expensiveOverall, great budget friendly option.

When it first plugged in it works ok, stopped working after first plugged in
