    Good quality. Poor performance!

    This non return valve seems to be well made. However, in the wind it clatters a lot, annoyingly! It is marginally better than the spring hinged type, but not much. It would have been better if the flaps were made of a softer material. It arrived on time, so no issues there!

    Less moving parts, far quieter than the hinged versions and will probably last longer. Sometimes the simpler solutions are best.
