Excellent for the price paid, pump has done what it's for, noisy a lot louder than some filters.

Perfect, does the job!

Does wh ast it says

Superb - did exactly as it's supposed to (not allow water back into the air tube, protecting the air pump). Definitely recommended.

Does just what it should do - stops backflow of water into the pump. ( Used in conjunction with Interpet Airvolution).
