Although it's only been a few days since I started using the Smart Water Monitor, I'm impressed. It was very easy to install, set up, and start using the monitor. I haven't had a professional compare the values using an actual water sample but comparing to some 3rd party test strips the values appear to be good. The app is great for keeping an eye on the water quality while I'm away and prior to using the hot tub. Overall, a great product and very useful for my purposes.

The new EcO Monitor is working great

Excellent service and product. They both work to the benefit of customers!

The calibration worked for us

I had a problem with my probe after ten months and they honored the warranty with a new probe and helpful advice

Replacement module for the EcO monitor

Simple to follow programmed steps and the probe fits nicely in the pouches of liquid for calibration.

Had an issue with my EcO monitor. They shipped one out right away, and swapping it was easy.

The EcO spa sensor and its companion hub performs its periodic tasks 24/7/365. In my opinion, it is the most economical device of its kind on the market.

So far so good! Working well!

The new monitor works great. Place in pool, checked water ph at pool store and read monitor reading and both were the same. Thanks for responding and replacing monitor.

I have a salt water spa the Caldera Geneva.
What a great saltwater hot tub by the way, but chemicals can still be challenging and expensive!
With the Eco start it’s a game changer.
No more mad scientist, mixing chemicals near the spa. This device tells you exactly what you need to add to the spa and then within an hour your spa will be balanced!
It’s really is that easy.
This device measures your chlorine levels and your pH level when both of those are correct very little things have to be done.
I’m stress free now, thanks iopool!

These test strips seem to be the most accurate test strips I have used.

Seems to be doing the job

I love this device! Easy to know my numbers and when I need to give attention to my spa. Living in Texas we get rain out of the blue and the temps fluctuates wildly. With my iopool, I know longer worry about my spa. With a Quick Look at the app I know everything I need to know. Data is king and iopool makes me the King of spa!

The support is outstanding as well.
