Great
These are easy to use and fit well with my aquarium bubbler we have had no leaky connection points, so these are great for anybody needing to put backflow valves into their tanks

Great replacement
In all my decades of owning a fish tank I finally had a check valve go bad. These work great and are easy to install. Pay attention to flow direction it's molded into the clear plastic.

Works great
These haven’t given me any issues and I actually had a power outage recently and no water came out of my beta tank so I would say it did it’s job!

An inexpensive insurance policy
These little guys work well, I only needed one but the six-pack was so cheap, it's an inexpensive insurance policy

Great product and needed protection
It's been years since I've used check valves on my aquarium, mainly out of laziness. I recently had some water siphon into my air pump and decided to buy these. They are so much better than what was available years ago. These use a rubber diaphragm/reed valve rather than the old spring loaded disc. Much better design and no air flow restrictions whatsoever.

Restricts air flow
I’ve had these a while and only recently got them installed. I’ve got 2 air pumps running on a bubble wand in a 38 gallon. With 2 of them running without the check valve the bubbles were strong and ran the length of the wand. After adding a check valve to each pump, there are now empty spots with no bubbles. It looks pretty bad honestly. I hate that I waited so long to try these because I should have gotten a refund. I’m going to need to purchase better ones that don’t restrict the air flow so much.
