I tell you I had my doubts. I really, really did, but it has proven to be everything they say. For anybody that has a pool spa hot tub, this is a must have. Good job, IO pools.

Perfect!
We were paying quite a bit for a monthly pool service where instead of actually treating the pool properly they would over chlorinate and barely clean the filter. I was terrible about checking the chemicals before. This has made it so easy and my pool looks great and no more burning eyes from excessive chlorination of my salt pool.

Spa and Pool on single app is convenient
Easy set up
I find the frequent pool chemistry checks helpful
The solution measure in spoon fulls was confusing
I think a spoonful is 1/3 cup

Kickstarting the pool season
Ordered the calibration kit to ensure everything was reading correctly before I started adding chemicals to open my pool for the year, super easy step by step instructions made it a breeze.

Great system and great company.
I received the Eco system last year as a present, and it work flawlessly all season. This spring I tried to wakeup the system and put it back in to service. But the Eco sensor would not stay connected. I contacted iopool with my issue. With in a day, they had reached back out to me with a couple things to try. iopool's also tried a couple things on there end, to no avail. The system was still under a warranty. Without hesitation, they sent me a new Eco sensor. Which I have up and running. My experience with customer service was great. I would recommend this system to anyone that has a pool.

Initial Thoughts on the Smart Water Monitor
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.

EcO Spa Sensor Performs as Designed
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.
