Review on Pawfly 7 W 254 GPH Adjustable Quiet Oxygen Aerator Pump for Commercial Use by Jamie Brady

This item is said to produce 16 liters per minute - In fact it produces about 1.2 liters per minute - HIGH! Low even less! I agree that the unit is quiet, but that's because it doesn't produce air! The device claims to come with a 4-port adapter, but it doesn't! It is shown in several photos and even several times in the description, but when you receive the device it is not included and does not appear in the instructions or in the photos on the box. Basically a TERRIBLE BLOCK!
