Bests & Worsts Reviews from Amazon

I am 100% pleased with the results. I had a slow drain kitchen sink that was progressively getting worse and was almost at the point of being un-usable. I'd tried hot water, bleach, draino, nothing worked. This product was my last resort before calling in a plumber and I'm glad I took the chance and bought it. I have a double sink so I used one treatment per drain, let it soak overnight and flushed with boiling water the next morning. Today I was able to do the dishes with absolutely no draining issues. What a relief!!! Updates: 8 months later and the sink is still draining perfectly. I cannot say enough good things about this product.
