Review on Walex Porta-Pak 'Lavender Breeze' Drop-In Toilet Treatment Deodorizer for Black Water Holding Tanks (Pack of 2) by Ricky Habbani

They're easy to use, come in ziplock bags, get the job done and make my life easier. We are avid hikers on wheels. We go hiking 2-3 times a month. We have a bathroom in the RV that we use a lot and I don't like the smells. Upon arrival at camp, once we're hooked up to the water supply, I'll drop one and do a couple of vigorous flushes. I haven't smelled yet. I love it. I used lavender but now I'm switching to citrus. I have no doubt that I will be happy. Yes, I am a "lucky tourist".
