Works as Intended for a Spot-Free Rinse
Incredibly easy to set up. Just attached it to a splitter on my outdoor faucet and it was ready to go. The water flow is strong, and after washing my car and letting it air dry, there wasn’t a single water spot in sight. You can really tell it’s filtering out the minerals. I also love that it includes a TDS tester so you can monitor when the resin needs replacing. Perfect for keeping cars, bikes, and even windows looking pristine

Great For Detailing Vehicles
My son wanted this tank to use when washing his vehicles so they would be clean and not have spots all over them. It easily connects to a water hose and instantly provides deionized water. It comes with a TDS meter to check water purity, and monitors the resin performance. When the resin is exhausted you can buy a replacement resin kit. It is a great tool to have for detailing vehicles.

Worth the money!
Really nice system but it would have been nicer if: 1. The fact that the TDS wand didn't come with a battery was no big deal, but nowhere in the instruction booklet did it state what battery (2032) and I had to come here to find out. Sloppy. 2. My kit was missing one of the quick connect fittings, we shall see how well they do with customer service. 3. It was a PITA to assemble-there has to be a better way to fill it with resin. So after all that it's a FIVE STAR. Works beautifully, drops the TDS to zero and no leaks, workable pressure and I'm a happy camper.

Spot Free Shine Every Time
It leaves my car spotless with zero water spots, just like a professional detail. Setup was simple, and the system feels very durable and well made. The water flow is strong, and I love how it makes rinsing so much easier and more effective. I’ve noticed a big difference in the finish of my car shiny, clean, and streak free.

So far so good
Like another reviewer, I bought this based off Car with Keav YouTube review. I spent a few minutes to cycle the water. I used a 5 gallon bucket to gauge how much water it took to get the filter ready. It took about 8 gallons to get the water to 0. Used for a final rinse on a 90° day at noon to make a worst case scenario and it worked great. As you can see on the hood, everything dried flawlessly. There were so minor residual leftover but I believe that was some soap left behind. Windows wipe clean and I only ended up using 1 towel to clean up some of the excessive water in areas just to speed up drying. Overall this will cut down a lot of drying time and I expect it to get even easier after a polish and ceramic coat. An absolute value as this costs half the price of name brand DI filters. Time will tell. *UPDATE* 2 weeks into owning this and I've used it as a rinse only twice so far. I use at most 10 gallons per rinse. Including my initial 10 gallon flush puts me at 30 gallons used so far. Started a 3rd rinse and noticed my ppm slowly climbing. So I've spent the next 10 gallons flushing only to find my ppm slowly climbing. It spikes when I turn the pressure up more. I even ordered a more reputable pricier tds tester which read pretty close to the tds meter provided. So all in all even if I round up on my gallons used to 50, I should still be reading 0 ppm. Totally bummed because this was a great price and absolutely perfect for size and functionality for what I needed it for. Unfortunately they don't offer a replacement. I have to return it and look for another.

Best budget water spot system
Easy set up. No leaks. Filtered water. Don’t forget to order a 2032 battery for the TDS meter

Filter not filtering all the way
I have a ppm of 370 without the filter and it goes to 100-200 ppm with the filter. Filter works well, besides the not filtering all the way. Maybe it works better if my water wasn’t so hard, but thats kinda the point of a filter.

Promising solution with potential
The Good… 0ppm from my city water which is around 250ppm. It immediately came down to 0 even before flushing the system. The Bad….. Leaking fittings…. Both the inlet and outlet fittings to the head are leaking. The head is made of plastic and i suspect the thread is too loose. The system came with a big roll of PTFE tape, very thick consistency. Its even hard to tear apart. Seems the manufacturer knows about this leaking issues. Also, the fitting on the inlet is to big and will scrape and hit the plastic fitting before being able to thread all the way in. I managed to reduce the leaking by using more than normal tape. It comes with a water tester (the white one). It comes without batteries and acts very weird, sometimes you can’t turn off. Potentials…. Better fittings overall, it comes with copper fittings, which is no problem, but don’t last, i been changing all my fittings to SS, well worth investment if you will be using the system often. Will be great to have a bypass, to easy switch between DI water and tap water. Currently i switch hoses, also no big deal, but would be a nice upgrade. Better handle, seems just cheap and installation is not fixed. A funnel to fill the tank. Although the opening of the tank is a bit wide, its very easy to spill the media. I have no doubt it will work and provide a spotless rinse, only time will tell how long will the media last.
