Worked as advertised worth the purchase
We are at a campsite in North Central Washington. The water is very hard. It tested the highest on the test strip I flushed the tank out per instructions, hooked it to my motorhome, waited one day to flush all the lines out in the motorhome tested the water once again. It was the lowest on the test strip. I am very, very pleased with the result! I only wish I had done this sooner.

RV water softener
Great water softener! Easy to use and makes water softer which saves money on laundry/dish/personal soap. Also the softener gives you healthy skin. This is the second unit we have purchasedโฆthe first model cracked at the top screw mechanism after 3 years of use.

I like it
I guess it works ,I had to use it temporarily for one shower to bring down hard water in a house until I can afford a whole house system ,everything is sealed and runs well ,so I put the wedduo filter on to protect the on the go ,and the shower handle has a filter and threw all that the tds meter I have says the hard water is 524 sometime 380 ,my meter said 700 before the system and the strips before the system tested in the purple 1000 range ,this is in Oklahoma city ,after the filter the strips that came with it says like 40 like it's clean but the tds tester says 524 so I don't know the tds meter on spring water no minerals test 0,23 but I have piece of mind until next year

Difficult to connect input hose to.
Works very well for hot tub filling. Water tests soft. Plug and play friendly. Included hoses needs to be longer. Also it is difficult screwing input hose on as connection does not turn, so you are literally twisting the hose to go on and can't get tight. Very heavy.

Extremely satisfied!
I researched water softeners for my new to me RV, 2024 Alliance Paradigm. I'm a water snob. The shipping was fast, it's made in the USA, and the price was great. Very easy to set-up. It is portable but heavy at the same time. First water test was great. But the proof was in the hair after my shower. Made such a big difference already. And, I want to take care of the plumbing in this RV. Hard water is a nemesis, on every level.

Perfect water softner for renters
Renting for the first time and live in an area with extremely hard water and I did not want to put in a filtration system for a house I did not own. I found out about this via a YouTube video by the water filter guru guy and he was spot on. I have this hooked up in my main shower and it has made the water feel great - silky and soft. The test strips show evident reduction in hard water levels going from 10-11 to a 1-2. My skin has definitely improved since I put this in 3 months ago but I noticed changes within weeks. Very easy to look after, drain and do a regeneration. I love the fact that it takes salt you can buy in you local supermarket and it's life cycle last years if you take care of it.

Top quality portable softener.
Love this portable water softener. We purchased it for our camper, and recharge it before each trip. Depending on the hardness of the water, you may get the a 4 or 5 day camping trip out of it, with taking daily showers, washing dishes, drinking, cooking, making ice, and lots of coffee (Yes, we have an additional filtration system before the water goes through the softener), or you may only get a couple days out of it before recharging is needed, but thatโs not a problem with the softener, itโs the water itโs having to soften. Typically weโre probably getting between 150 to 250 gallons of softened water before recharging is necessary. Recharging is time consuming, but not difficult by any means. I love that our sinks and toilet no longer turns rust orange after just a day of using hard campground water. Great quality, and compact enough to fit in the camper pass-through stowage compartment.

Does a great job
Great product So easy to install I added some quick disconnects so it makes it much easier to do the regenerations I will also add a filter in front of the conditioner to remove sediment Itโs been in service now for about 3 weeks and the difference is amazing Highly recommended

Works great!
Easy to install. Easy to follow instructions. Just completed my first regen. No problems. Be aware that you'll need somewhere for the flush water to go. Our setup is outside where I have a gravel area to flush into. Went from over 250 ppm to 0 with this unit. For 2 of us in our park model trailer, we're required to regen every 21 days. Using a box and a half of table salt each time. Working great for us.

Easy to hookup and regenerate
Bought one of these for our seasonal mobile home. Well water is the where the water source is from. The water was very hard until we hooked up one of these. Hookup and operation is dead-simple. I used to boxes of table salt when I was ready for regeneration of the water softener and just like new in 30 minutes back to soft water again. Highly recommend!
