Helps where other means fail

Bin on this product come because of reviews. Our toilet was clogged, the water ran off only slowly. The usual budget and also an outflow funds from the hardware store for 10 failed to work. Also from an expert recommended home remedies (detergent and buckets of hot water) was no more. At first I was skeptical about whether it is useful, since in the existing water pours means the toilet. The application was used exactly as directed a great success. Thus, the relatively high price justifies. Because it is more than 90% sulfuric acid, you have to be very careful.
