Review on Aquarium Reegugu Rechargeable Portable Powerful by Tracy Pederson

This is a great little backup air pump in the event of a power outage to the aquarium. .It's fairly quiet and delivers a good amount of air bubbles from the included stone. The included instructions were useless if you couldn't read Chinese. The button was a little hard to press as you can see in the video and I have no idea what did the first press that made the blue light come on. A second press turned it off. Otherwise it's a good little pump, perfect for emergencies.
