I happen to purchase this as a back up and I was excited when I opened it to test it out little did I know that the air pressure was probably only for a 5 gallon tank I literally had to play around with the batteries in order for it to work. Let me give you some advice. Everyone do not buy this air raider.
It is very, very noisy that it will really disturb the peace and quiet atmosphere of your house. More so, it doesn't generate much air producing less bubbles in your aquarium. Buy the black Marina brand instead.
I bought this several months ago for emergency use this winter. Now that the weather is changing, I decided to test it out. Opened the package to discover the soldered wires have come loose from the contact point. This is something I cannot fix, nor should I have to with a brand new item.
This did a great job keeping my 50 new rescued platy fish healthy on the car ride home! Good to have for power outtages too.
Fast shipping , awesome for power outage , My fish thank you!
I bought this, the very next week my electric went out for 2 days. Without this handy dandy item my fish would have died
