HiLetgo 2pcs Water Pump 240L/H DC 12V 4.2W Micro Brushless Pump 3M Pumping Head Ultra Quiet Water Pump for Pool Aquarium Fish Tank

Quiet, pumps well. Picked up a 12V AC/DC wall wart from the bin at goodwill for 5$ to run it, soldered it on, runs great. Uses 1/4" ID hose. I bought it as a miniature sump pump for a problem corner on a patio, and it is driven by a water level sensor, this is where the wall wart plugs in.

I've built an a/c out of a cooler and I'm using this pump to circulate ice-cold water through a computer cpu radiator/fan. It appears to be built well and operates quietly. It has enough water flow to cool down the inside of a small single engine airplane. It has lasted about a year now which is more than I say for other products I purchase. I believe this is a good value.

These pumps do not work at all. They could not even pump water on a horizontal surface I can’t believe any reviews on these things Absolutely terrible

Great little pumos for the price but quit working in less than a year. They are cheap enough that I just bought a other set to replace the dead ones.

These pumps are the perfect size for small projects and work exactly as advertised. Just make sure to only run them on the 12V they’re rated for, and they’ll perform beautifully. I use them to circulate water for my quail, and they’ve been running quietly and reliably without any issues. The price for a 2-pack makes them a fantastic value, and I’ll definitely keep a couple of these on hand for future setups.

Awesome little pumps. I use them for duck hunting so they get beat up and suck in mud/grass. Have been reliable for a few seasons

You get what you pay for, theae are cheap in cost and ability. But if you treat them correctly they will work But don't let any debris get in, the pump will seize up and you need to remove the tiny 4 screws and remove the debris. However, because of the design, clogging the pump and causing it to seize will not hurt the pump. The pump.needs to in the chamber to work. One little air bubble and the impeller will spin ans not pump liquid.

Used for aquarium water change equipment and works perfectly. Very quiet, reliable and pumps great.

Great little pump! Very happy

This pump is great. It's small a in size but powerful in its pumping. I am using it to pump dehumidifire condensate to drain.

These pumps can run off Molex and work pretty good for PC water cooling.
