Especially for the price, these check valves are great and every air tube that goes into the aquarium should have a check valve.

This check valve works fine for me. I have had no problems with it thus far. I would really recommend it to anyone who needs a check valve. It is well made and easy to install.
Works great for me! I haven't had any problems from it.

I did not care for this check valve. After receiving it, saw the poor quality did not even use it

This item did not work for me. It caused a major leak on my floor. I would not recommend. It deserves no stars but I couldn't submit without putting a rating, so I chose half a star.
