Review on ALEGI Aquarium Cylinder Bubbler Hydroponic by Jennifer Wilson

Mixed feelings at first, they come in a pack of 2 and one worked fine and the other didn't... even wrapped in foam for extra protection. GOOD! But even with this extra protection I think 1 wz will be damaged in transit. Although there is no visible damage to the box. One end of the vent separated from the vent material, allowing most of the air to escape at that end. In any case, Revain was quick to send out replacements once stock ran out. This resulted in a one-week delay. But now everything is fine and I couldn't be happier with them. At the time of this writing, they have been with HV for several months.
