I am now in my second season with WaterGuru - Sense. I have found it is easy to use and it made a huge difference with checking the balance for my inground pool. I know this technology has been around for years with friends having full computer systems monitoring their pools. However, not everyone has that kind of budget. Every morning I get the report for the day at a time I set to check the chemicals. I then make the adjustments, quick and easy. There are additional things that the Sense checks which saved me a huge heartache last year. The Sense also monitors the pump flow. As it turned out my pump was beginning to fail. I was able to replace it before total failure. Big win. There are changes that I would like to see. Real-time temperature sent to the app without having to use the consumable cartridge. In summary, a must-have for most pool owners.
