Fabulous for RV life
We absolutely love our softener! I knew after a week of RV life and the water we were gonna need one. Thankful this is local to my state and proud to support a small business! It works beautifully, my only downside is that i should of gotten the larger size since we RV full time. Thank you for a wonderful product!

Perfect for vanlife!!
Had the larger one with our Class A RV. I was a little worried that this would be too big for our Class B, but it is perfect. We have a Coachmen Galleria 24A Li and it fit perfectly behind the Lithium Battery and garage door.

Great softener
We winter in Southern Arizona in a 41 ft. 5th wheel. The water is super hard and my hair became super dry. My shower doors became white and scaley with hard water deposits. Not any more!! My hair is so soft and no more spots! We have to recharge this every two and a half weeks. It is great because it only takes a box of table salt. Very easy to install and keep up. We have a filter installed before the softener and a pressure valve as well.

Perfect for Apartments and Skin Problems
I had another version of a water softener for my shower, was suppose to be good for 10 years. After 6 years, it finally said enough. Would have had to spend the same amount that I did for this one on that, only to have to throw it away again after 6 years. This On The Go Softener is a perfect size for my apartment shower. Yes, it does take up some real estate in my tub, but for the benefits that it gives me, I'm willing to work with it. Emailing the company bought an immediate response to my question on how to hook it up to my shower. It has done wonders for my eczema, to the point I don't have to slather myself with prescription creams anymore. Add to that, the plus that I can transfer it to a camper (when I get one) and always have it with me, plus being able to change out the resin beads if it is ever needed, will make me come back to this company again.

It works better than I expected
I'm camped in an Idaho State Park with the world's worst water. It's so hard, I'm sure it's bulletproof. There is so much iron in the water that it runs about 2 shades lighter than apple juice. It was staining my sinks, shower and toilet and on top of that, it smells awful. My two-stage water filters did nothing for me.At the recommendation of the camp host, I bought this water softener and added it as the last stage before my water inlet. What a huge difference. There are no odors, the water has no taste and it is as clear as bottled water.It was shipped in a rather flimsy box with very minimal packing. It looked it got bounced around a bit by UPS, so expected it to be damaged. I photographed it before opening the box and to my surprise, it was intact with no obvious damage. The O-ring that seals the cap to the bottle was not properly seated, so it sprayed water everywhere when I connected it to the system. I was able to re-seat the O-ring and connect it to my system without any further issue.
