This absolutely works and does what it says. Pretty amazing with such an easy fix. I use 2-3 drops at a time and it works well. It doesn't mask the smell it eliminates it. I've tried the three combo pack and each scent is nice but, not over powering. When you flush it still covers the smell and leaves the bathroom with a nice pleasant odor. I recommend it highly! It's like the old saying "my poop doesn't stink" now it's not just a saying, it's the truth!
