On The Go OTG4-VM-DBLSOFT Review of 2023

1. Capacity

This is a 16000-grain unit and as per the manufacturer, it provides soft water up to 1600 gallons, which is basically an average of 40 days. And, we can say that this is completely true. You might be surprised at the capacity after having a look at this marine water softener because it appears so small and yet provides more soft water than any other water softener in the market. On The Go RV water softener doesn’t require a frequent change in salts to regenerate itself, and hence runs for a longer period of time than other models.

2. Salt-based Type

As per the manufacturer, OTG4-VM-DBLSOFT On The Go 16000 grain water softener simply regenerates with 2 boxes of common table salt in less than 30 minutes. The work of the softener is very efficient despite the fact that we haven’t had the chance to change the salts more than once. So, once you change the salts, you won’t have to worry about it at least for a month or so. Certain people might find this tiresome, but honestly, after seeing your skin fresh even after long hours of washing dishes and clothes; you won’t have any complaints, that’s for sure.

3. Design

Ironically, On The Go double standard water softener is the largest compact model when compared to other standard models. It is built for anybody owning an RV/Marine model and has brass fittings as well as plastic fittings with high-grade premium resin, plus the user-friendly installation process makes it a perfect buy.

The best part is, it gets easily fitted in the tightest of places and anyone having a comparatively smaller apartment or place to live in can also easily install the product. It has an easy to carry handle on the top, a large mouth opening to add the salts easily, and a travel-friendly option of cap and plug to prevent leakage. The lithe design makes it an all-rounder device in the sense that one can carry it around or put it inside as per their requirements in a single buy.

4. Flow Rate

This has a flow rate of 3 GPM (gallons per minute) and is higher than most average shower head flow rate. On-The-Go Large Compact water softeners provide soft water with low-pressure drops and are claimed to prevent rust stains. We can assure you that just because it makes the water soft, it nowhere near hampers the flow of the water. The excess amount of iron in our area created a very rusty taste and odor in the water. That problem has vanished. We can never thank enough for this improvement in taste, also now we don’t have to worry that our appliances might get easily rusted.

5. Warranty

The On-The-Go softener “-comes with a one-year warranty period from the date of purchase. In short, you have a money worthy product in your hand. The benefits with the overall cost make it a worthy purchase. Think of it as having zero workmanship expenses for a year and also having fresh soft water that keeps your skin and hair perfectly fine. They even provide us with an instruction manual so that everything becomes very easy to understand. They provide assistance in whatever way they can. So, don’t worry, in terms of money and efficiency, we can say that this is the best water softener on the market.

We would like to list down the things that we think are great about the product and things that are not.
