Shoe broke second time wearing. Now it looks like an ankle bracelet and her heal comes out of the shoe every time she takes a step.

This lil doohikey is amaze balls! Great little pump. Only have two complaints and they are exceedingly nit-picky.

Flow rate is great, the size is impressive, and the ability to use usb power is great! It filters my 3 gallon very well.

It runs pretty much silently and at full power moves an impressive amount of water for it's size. The speeds are adjustable and it remembers the speed you set it to even if you remove power for a while. It has * on back and led of blue lights.

Using a 10,000 mamp power bank allowed for several hours of localized cooling for very decent comfort. A small usb power block and this pump does the job just fine. I have it circulating water into a 240mm radiator on a homemade cooler a/c.
