This valve is absolutely the best one I've used. The other versions of them are too cheap of a plastic to last very long. Not only that the seal that they have is air tight.
seems to work well.
The valve works great. You can let the air flow open or even cut the air completely. It gives you total control of the airflow rate.
Great price and Great Service
Excellent product. Sweet price!
set up a sponge filter
works well to control flow.
Haven't used the product yet but the items arrived quickly
Easy to install, easy to use. The large knob is very convenient.
my husband works at a local pet store with a small fish department. He has brought home the airline valves they carry, they are cheap plastic and often not very functitonal. The Ziss valves are solid and well made, easily adjustable and very effective. Definitely a superior product!
