Very simple to use...simple to install...great value. No sense to filter water through an RO unit and not know if the RO unit is making a positive impact to water quality. This unit make that analysis very simple

Super EZ to install. I have it after the RO then at final output as suggested. Works like a charm. I had purchased a used RO/DI unit and this meter takes all the guess work out changing filters.

Works great easy to set up comes with velcro to mount it on your ro/di system or somewhere else. Only con is it feels cheap it would be nice if it was made out of a metal box or harder plastic pushing the on button makes the whole front panel bend in. So it feels like im going to break it lol other than that works great.

It was easy for my wife and I to get this piece mounted on the wall and quick to start. It read very well the first time as it updated our input and output very fast. I would recommend this product to all, including beginners.

I've had one of these little guys for about 4 years now. It was worked flawlessly and I've never replaced the battery. I love not having to guess when it's time to replace my filters.
