(5/5)

“Very convenient …”

“Very convenient way to keep pool water properly conditioned. I also learned how leaves and rain affect chemical balance of the water.”

Larry Q.

“I’ve already recommended it …”

“I’ve already recommended it to my dad. The team behind WaterGuru is extremely knowledgeable and this type of device can revolutionize the pool industry. I have personally gotten great support from the team on any questions I have.”

Erik B.

“Setup is easy…”

“Setup is easy and not a hassle. While it was working, I did a comparison with manual chemical Test. It looks pretty accurate and a potential time saver. So I don’t mind continuing. One feedback: is there a way to request measurement instantly? It looks like the device only measures the chemical at a set periodic time.”
