My husband complained about the 'sour' smell in his bathroom. After thoroughly cleaning showers, floors, sinks, etc. he still complained about the smell. I bought this product, used it as directed and the next day, voila! the smell was gone. Neither he nor I could smell a 'mint' fragrance, but that's fine. The sour smell was gone. I've used it a couple of times since to prevent the smell from coming back and we haven't had the problem since I purchased it several months ago.

I purchased this for our kitchen sink that has a bad smell. My hopes were not too high, but I added this to the sink on day 1 and the following day the smell was gone. I thought the smell might come back in a few days, but no. it still smells like mint and I love it! I did it a second time just to be on the safe side and the smell has completely went away. Definitely worth the money, and I will continue buying this product.

Smells amazing and it did the job. Drains were not blocked but not smelling great. Excellent product

Great product but it is a bit expensive for how much you use per drain. It did help clean up our drains though and they just smell so clean now

So far I'd have to say that I don't find this very effective on my slow running kitchen drain. It is easy to use and we left it in the drain overnight and followed up with a hot water flush, but the drain still has problems. It may be a good product to just keep your drain running clear. On the plus side, it is pleasant to use, and has a great minty fragrance.
