I have one of these for my small 2.5G tank at work and another for my 5G at home in my bedroom. Both work fantastic and are super quiet. I actually hear the bubbles popping on the surface of the water over these pumps. Highly recommend getting the Never Clog air stone, check valve and Ziss air valve along with these pumps if you're setting up a new tank. Allows the ability to adjust the size of bubbles/flow rate easily.
Both of my little pumps have been reliable and quite useful in application. Shipment was fast; shipped day of fast (good hustle).
This pump is amazing quality and really is dead silent. Comes with the usb block and cord so is ready to go out of the box. Super handy and great to have.
Quiet and works great. Only wish it had a built in battery but of course that would make it quite a bit more expensive.
I've seen this product on the YouTube channel so many times and I wanted to see it in action. I wanted to try it for my 7.5 gallon betta tank because I wanted an air stone to produce a little surface agitation. Very quiet and when combined with a never clog air stone and Ziss control valve I got the desired results. I also tested it on my medium bar air stone and it was able to produce enough air. Also it is VERY quiet in my opinion.
