> 3 dayAs a new RV owner, having a clean black tank is something I need. It works just like the videos show and never had to worry about leftover nasties. Super simple to use and I know my tank is clean. Spend the extra 50 bucks, you wont regret it.

Greater than one weekIm so glad I got this while my RV was still new, otherwise I would have just assumed that the black tank indicators werent fully reliable. Using this I now realize how much matter is left after draining the tank - mostly toilet paper even though we use the RV stuff that is supposed to dissolve. I empty the tank, then close the gate and spray, partially filling the black tank with water. I repeat until the indicator light shows the tank is empty - which can be 3 times, but it doesnt take long at all and is really easy to use. I got a black hose so that there is no mistaking it for the potable water hose. One of the best RV accessory purchases Ive made, absolutely essential.

> 3 dayEmptying your RV’s black water used to be a chore. Not any more, thanks to the folks at Camco. The Camco Rhino Blaster turns tiresome into awesome! Coprophiles of all ages will enjoy this unique product, which combines the old-fashioned suspense of Jack-in-the-box with the visual fascination of that video of your last colonoscopy! The whole family will want to gather around and watch yesterday’s stinkpickles slither away through the Rhino Blaster’s unique clear plastic elbow. But that’s not all. When will the Rhino Blaster’s seals give way? Nobody knows, but when it does, giggles turn in an instant to screams of delight as the Rhino Blaster showers one and all with a warm spray of juicy man-manure. And the Rhino Blaster puts the gag in “gag gift”! Give it to that annoying neighbor and then set up your video recorder, because you’ll want to watch over and over again as he gets a fetid faceful of human guano. Thanks, Camco! Five stars and two enthusiastic thumbs up for the Rhino Blaster! GMO-free and naturally low in sodium! So, seriously, this product was great until it blew apart on the 3rd use. The swivels where the parts are joined together are not made well. I ended up sprayed with human waste.

> 3 dayThe one I got came broken, the valve that controls the water from the hose came broken as in it wont turn on/off, its constantly on and slightly leaks. However, my black tank had a blockage at the drain valve and I was able to use this product to successfully and quickly back flush my black tank. Only reason for not 5 stars is because it came broken, otherwise a perfect product. Hopefully my next one will be flawless ☺️
