It improves the water flow. It is a well recommended product.

IT clears the clogs every time whether it is the kitchen, bathtub or bathroom sink

Tried using the product on a shower clog, it did not work

I used a bottle and a half on bathroom sink and still plugged

was a great product cleared the problem right away.

Purchased to clear tub and kept drain clear for an extended period

Always works for me. Pour into drain and clear with hot water

Worked quick on my bathroom sink! I have full confidence that its going to work.

Did exactly what it was supposed to do. Unclogged my clogged shower drain!

Not as good as Drano Gel.
