I purchased two of these units. The first one I had to soder the circuit board power source in the 12 volt plug. After running it for 20 minutes the tiny little pin that holds the gear in place came lose and the unit no longer was pumping air. Do to the change in the sound of the unit running I was Lucky not to lose all my bait. The second unit worked a bit longer but then quit pumping if the bubble stone dropped more then 5 inches in water. I will not purchase this brand again unless they make some major changes to design. I liked the idea of the 12 or battery but the product does not hold up.
