WaterGuru Sense S1 Smart Cassette - 3 Pack - Compatible with The WaterGuru Sense S1 Smart Pool Monitor only - Chlorine & pH Pool Water Testing Smart Device

Great product!!

It is so nice to have my pool test itself every day. I don't have to worry about the chemicals until my phone alerts me to add acid or choline. I can alert our house sitter to add chemicals if we are out of town. Works well.

*******Overview*******The WaterGuru S1 pool sensor cassette effectively measures temperature, pH, chlorine, and flow rate, providing accurate readings for basic pool maintenance. It does not however give all the functionality the S2 version offers.******* Warning*******Note that this cassette is intended for the older S1 model. For additional testing capabilities like acidity, calcium, and alkalinity, users with the newer S2 system should consider the S2 C5 cassette or the S2 3-pack option. However, these don’t appear to be offered through their Amazon store but can be purchased on their website for the same price.I have attached a screenshot highlighting in blue the tests you get with the S1 version of the cassettes and red for the S2 version of the cassettes.*******Message to WaterGuru*******A drawback of both these cassettes is its daily testing requirement via the WaterGuru app, which depletes the test strips within 30 days, pushing for frequent replacements and added expense. Allowing adjustable testing intervals could enhance flexibility and extend cassette lifespan, although this would likely impact your company's revenue from recurring sales. Maybe survey your customer base to see how many use this product 365 days a year. You may be able to increase margins by offering different different testing intervals so customers can opt to test less frequently in low use seasons like winter.

First of all — I love my Waterguru sensor! I Maintain a pool for work and this is helping keep our pool balanced and sparkling. We have a somewhat local place we can take our water for testing — it is pretty accurate!!Kind of expensive for the pods, but I see the value in my time

After my pool service raised prices in 2022 I decided I needed to sit down and learn to get my pool chemistry correct. I came across this product and I decided I would give it a try. The first box I received was clearly used, and I was not too happy about that. I returned the item to Amazon and they sent me a new unit. Setting it up was a little difficult. It seemed not to want to connect to the wifi but after some time I was able to get it to connect to BT and get it going. It now is connected and has remained connected since. I simply just listened to what the device had to say. It gave instructions on how much chemicals to add and I just followed its directions. When it came time to send in a water test it took some time but the result eventually appeared in my APP. This was cool. I followed the recommendations after the results and my pool has remained crystal clear. One thing I like is that it does do daily tests. I get notified when the FC is low and I never go zero. For this last test, I changed my water in the pool due to its high levels of CYA. I decided it was time to change it anyway since it had been more than 5 years. I filled the pool and took a water sample. When I got the results it gave me all sorts of info on balancing my water. I followed those instructions and I continue to have clear clean water. They have a new unit that reads many of the levels that you normally would have to send in a sample. My unit is only 1 year old so I will wait a couple more years and I am sure I will upgrade. Even with the 20.00 a month charge for cartridges, I save a 100.00 in what I was being charged a month for a service.

The water guru system has been a wonderful resource for my pool. Having the live data at all times changes the way you deal with your chemicals. I don’t ever want to be without it!

By the time I needed to use these (They each last 2 months, so I just now needed to change cassettes), I found out that they do not work!!! I tried a second one and it too is non-functional! I want a refund, but Amazon says "the window is closed". I feel like that is unfair since I just now needed to use these.

I have used this system for three years. The convenience of the daily readings has got me spoiled.
