Overall this stuff does exactly what it's supposed to. It gets rid of smell and waste buildup and it's the best I've used for our trailer tanks. It smells rather chemically though, much like a Port-A-Potty but it's better than the alternative of course. Just be prepared for it to to smell pretty strong for a bit, and have windows open to help it air out.While it can be nice to purchase in bulk, I wouldn't recommend getting the gallon size. I won't again as pouring it can be very unwieldy and it tends to spill down the sides. I'll probably get the 4oz 6-pack next time, but I will be using this from now on for sure!
