BornFeelBornFeel Aquarium Air Pump Splitter 7 in 1 Set 2-Way Air Flow Control Lever Valve & 2 Non-Return Check Valves & 4 Suction Cups for Fish Tank Airline Air Tube Hose

I have three tanks split with three sponge filters and the splitter is amazing. I can get very nuanced control of the airflow. I also like that they threw in some extra check valves and control valves. You always need those

Works well but had to buy a new black piece cause the one it came with had a hole when it arrived

work as advertized

I LOVE this item it works as I hoped it would.

Didn't try the suction cups but it does what I paid for at a low price. Just wish it came with directions, i used the amazon pictures to see where and how the pieces go in. Kind of tight going into the tubing and couldn't get it in the tubing all the way. It is a little tight to turn the knobs as I need them to only push a small amount of air as I am using it in my sea monkey ocean tank. Now I don't have to manually aerate so I'm happy about that

Works as it should. I use them for all kinds of things. Like drip acclamation, air adjustment, and diy does control.

1 check valve just doesn't work and lets back-siphoning. One of them is has a huge resistant compared to the other working ones. But overall, I think it's a good buy for the price.

not super happy with this product. the valves are all messed up and very sensitive to adjustment. i have 2 lines going out with the last outlet closed. the air flow goes to one tiny sponge filter and one air stone and the flow absolutely sucks. i know it’s this valve and not my air pump bc i tested the air pump on other valves/equipment. so i wouldn’t suggest this specific split.

Does the job as needed
