  • Lasted less than 3 months
Size: 7' inch
The membrane is great and puts out a lot of bubble distribution. The weight is sufficient to stay in place. The plastic connection is garbage. There are no replacement options for the barb that I can see. I was taking it out for the winter and the barb easily broke off. $53 gone. Other bubblers have replaceable connections which are necessary due to pond usage and importance of durability. Matala makes greats products IMO, this one needs an entirely new design. Avoid!
