Item worked well till the first battery change. Now will not work with the flow meter. Died after first battery change. No instructions on-line, useless manufacturers website. Now about as usefull as a calender. Lame at best
Extremely useful, but could be more user friendly By Marc on 3/31/2011

I purchased this as part of the deluxe system. It's extremely useful as it takes the guesswork out of how much water has passed through the system, as well as how long it's been since the filters were changed. It contains five different alarms; each controllable by time and/or volume.
Just beware of one thing. If you need to change any of the parameters do it before using the unit. If you change a parameter it will reset the counter for that item. It would be much better if you could change the parameter without necessarily resetting the counter.
Not worth it By Mark on 12/11/2010

I should have done more homework on this one. Although it works as advertised it does not help monitor your water quality as much as a couple TDS meters and clear canisters to see when the filters are dirty. Spend your money on more filters and don't bother with this meter.

This is great!...It monitors 5 different stages and lets you complete control over the setup up for each stage. Tracks time and total water usage. Alerts you the proper time to change your filters. Very easy to use
No guess solution for tracking filter use. By William on 3/26/2010

I would highly recommend this filter monitor if you have a RO system designed for Chloramines. It takes the guess work out of tracking how much water has gone through the different stages of the filter. Also the unit is quite compact.
