Biling Solar Pond Aerator 1.5W 5V Solar Pond Air Pump 0.8L/MIN Oxygenator Solar Powered Pond Aerator with Pipe Air Bubble Stones for Outdoor Garden Fish Tank Pool Small Pond

The media could not be loaded. Produced a steady stream of satisfying bubbles when I first received it when it was sunny weather. The description claims the product will run day and night subject to receiving sufficient sunlight during the day to power the battery. Pump just buzzes intermittently in overcast weather. It would have been fine if the description clearly states that ample sunlight is needed (common sense anyway) but why go the extra step and make promises that cannot be fulfilled? My advice to prospective buyers is don't be fooled by the appealing description seeking to tantalise you into a purchase. The product is just like any other solar air stone so on that basis I would purchase from a more reputable seller with higher number of reviews.EDIT:After initially giving two stars, I have to say I had originally been rather harsh. The airstone and aerator are fantastic keeping water clear. I have two different outlets from same aerator feeding off to two different water features and they are performing really well. Worth spending the extra and having something reliable. I stand by the fact the description can be slightly more accurate but the aeration continues into the night if the day is sunny. Can't be too harsh, I am impressed not going to lie.

Had this pump set up for 13 days, and very disappointed with the quality. We're having a beautiful sunny April with bright blue skies, but the pump fails to work. I've tried it with two air stones, then reduced it to just one air stone, then tried swapping to the spare airstone.. I also tried reducing the length of the tubing. It's just useless, no bubble produced at all. Would not recommend.

Works beautifully and is exactly what is exactly as described. Very happy.

Initial product did stop working however, the issue was quickly resolved and a replacement provided

It came fully charged and drained the battery on the first still day but just a few short hours of direct sun in the morning was enough to fully recharge while running on the low mode. This last week it's been full throughout and we've not had much sun.The first con I noticed was how the solar panel attached to the stand, it basically slides in and balances and theres no rotation either. This means you can't turn it or flip it to follow the sun. It wasn't a bother since it charged easy with the just the morning sun before moving out of range.That said the con turned out to be the failing of the product as the first bit if wind and the panel must have caught a gust snapped off and broke the stand too. Left it hanging by the cable. Wouldn't mind if it had been a gale but it was just a mild summer breeze, my fountain panel had been up 2 years just fine through storms but that's made real sturdy in comparison.That aside the power of the motor is amazing, the low setting gives a great amount of bubbles, I slightly tweaked the length of the two tubes so I could get bubbles at two different heights as my pond has two depths and the adjustment to the recommended worked perfectly. It recommends to cut the same length and have at same depths to get bubbles from both stones, it's physics 🤔I was really impressed with the low setting and didn't get chance to try the other modes.I would buy again if the panel had a better attachment to the stand and a stronger stand.

Great value for money , works really well easy to assemble.

It worked well for the first month, it then stopped working at night, as the days drew in it wasn't charging the battery and only worked in direct sunlight, but for the last week it hasn't worked at all, it won't change from theintermittent mode and is not producing enough power to create and bubbles even on a sunny day. I've tried cleaning the stones and tubes etc and it makes a faint noise but does not produce any oxygen. Only got six weeks use out of it so very disappointed as it advertised it would work in cloudy conditions and at night.

works well but should have option of black tubing
