Rated 2 out of 5
from Shipping costs are a killer I needed to buy 4 replacement flow diffusers, and the price looked good, but then as so often happens, the cost of S&H more than doubled the total price. If I could have found them anywhere else, I would have gotten them there. The original product is great, I've had my power heads for years, just hope you don't need to replace a flow diffuser or an impeller because that is going to cost you more than it should.
