Does it's job
Exactly what I needed for my aeration septic system.
Just what I ordered. Used them for years
Does the advertised job.
Recently switched to this product from another name brand on the market, so to be fair, I can't comment on the actual product's use. But from the perspective of product cost and vendor service I couldn't have expected any more - very reasonable price and fast shipping!
