Pleased. This is enough to move against the flow of water from the filter. They "glow" properly at night when the blue LED in the aquarium is lit. They look alive and the colored part of the flower has not shed even though they have been in the aquarium under a constant stream of water for more than three weeks. I see no reason to believe this will change in the future. I am very, very satisfied with this product and can only recommend it.
