Review on 🐠 Uniclife Battery-Operated Aquarium Air Pump with Air Stone and Airline Tubing - Portable Outdoor Fishing Oxygen Pump by Beth Walker

I needed these bubblers for a long trip from New York to Florida that took about 18 hours in total. They are a bit noisy but I had music on the whole trip so I didn't hear it. I tried using them on my two fish that I took with me and it didn't work. I bought a huge pack of new batteries for them and figured I wouldn't have to use them as the description here says they last 40 hours or so. Even new, high-quality batteries run out very quickly. I changed the batteries twice in each of the two bubblers and one of them died before we arrived. I checked them every 4 hours to make sure they were still working and half the time one of them would fail. I ended up running out of batteries so one of them was permanently sitting on top of the rest of the drive. I kept changing the working bubbler between buckets so there was oxygen in the water at least every 4 hours. In short, both my fish survived (albeit with difficulty) but it took them a month to recover. I only recommend this product if you're only going to be using it for a short time or have a TON of extra batteries with you.
