“The WaterGuru Sense has made my life so much easier and my pool chemistry has never been better. I only focus on Free Chlorine and pH, since I take a water sample to the pool store almost every week and get a complete analysis for everything else. This product is perfect for that focus. It is everything I have always wanted for maintaining my pool chemistry. So worth the cost and periodic cost of a new cartridge, but without the subscription fees of other products.”
