The system works great for rinsing my RV! We have a large RV and with this system i don't have to worry about water spots on the finish. We live in the country and have well water for our water supply. Mineral spots have always been a problem for washing cars and our RV. The system leaves no spots and makes it so much easier to clean and it's a walk away after we rinse our vehicles.

CR spotless always helps with the drying process. In AZ we have seconds before the water starts drying on the cars... this makes washing cars possible in the AZ summer.

Easy to install. When you order the cartridges make sure you also include the top spacers.

This product is great for a short period of time. The water where I live is very hard. Last cartages I bought only last for a month a were only 3/4 of the way filled with resin. It works great for a few washes (5-10), but the filters don’t last long enough and are $150 to replace for 100-150 gallons of treatment at most. If these treated 400-500 gallons, I think they would be totally worth it.

I got maybe 4 car washes out of a set of two filters. What a waste of money. Bought in February and used from March to October and getting 360 ppm and water spots. I've had resin from other sellers last 20 washes over about a year and a half span and no spots.

Living in Lemoore, CA, where hard water is a persistent issue, I was eager to find a solution to simplify my automotive detailing and solar panel cleaning routine. Sadly, the CR Spotless RC2-20 Replacement Cartridges fell significantly short of my expectations.Despite the initial promise of delivering spot-free cleaning with hard water, these cartridges proved to be disappointingly short-lived. After merely five automotive detailing sessions and a single cleaning of my solar panels, the filters were already depleted. For the hefty price tag of $140, I anticipated a longer lifespan and more efficient use.The idea behind these cartridges is excellent, and while they did deliver on the promise of spot-free cleaning initially, their durability could be better. Given the cost, I expected better longevity, especially considering the prevalence of hard water in my area.Regrettably, I cannot recommend the CR Spotless RC2-20 Replacement Cartridges due to their limited lifespan relative to their high cost. Unfortunately, it's an investment that did not live up to its promises.
