WaterGuru 4+

I love my Sense 2, which I use to monitor the chemistry in my salt water hot tub. I used a high quality digital PH meter to compare numbers with the Sense 2 and the results were within the margin of error for both devices. Chlorine readings from the Sense 2 closely line-up with the colors on two brands of test strips. Now I don’t have to constantly mess around with test strips to keep my water balanced!

I only gave 4 stars for some reliability reasons, but I would give 4.5 stars if I could. The device can be a bit fickle about connecting to my WiFi network, but those occasional problems eventually get corrected. Also, I’ve experienced two power supply issues with devices that required the devices to be replaced. On a positive note, customer service from Water Guru has been truly outstanding and my defective devices were quickly replaced.

This product was delivered to me in a timely fashion, but never functioned at all. Despite repeated (dozens) of requests for customer support over the past 10 days or so, via email and phone, the ONLY response I have via email was that someone would be back to me within one business day. This was several days ago. This product is a brilliant concept, but these people will not be around for long without any customer service, whatsoever. Don’t waste your time and energy here. Someone else will build a mousetrap that actually works. July 11, 2021 An update to my earlier review. Finally received some customer support. They made it right and got me a unit that works. It appears to have been a defective cartridge. The unit has now been working as I hoped it would for about a week now. If this continues, I am happy. The story from customer support was that they have been inundated during their busiest season. Not a great excuse, but leaves hope for future improvement. I’ll update again in a month or so. Stay tuned. August 26, 2021. An additional update. The product has now been working flawlessly for about 60 days and is doing exactly what I want it to. Customer service was very slow to respond, but eventually made things right. I will now recommend this product wholeheartedly. Hopefully, you won’t encounter the difficulties I did, but if you do they will make it right, even if it takes a while.

Hi! Thank you for updating your review and for allowing us to address your concerns with your device. It's also great to hear that you are happy with the service your SENSE unit provides. Have a nice day!- WaterGuru Social

Read this review to the end!
I bought a Sense unit a few years ago. Last year I upgraded to a Sense2 because I was having trouble with the original unit. Unfortunately I could never get it to operate properly and so I’ve spent the past several months emailing and live chatting with tech support, all without resolution. Then someone gave me a phone number to call and I met WG employee Miss Joan. She stuck with me and called me back multiple times through several issues I had. She discovered my app was trying to connect to the old unit! She helped me connect it properly and now it’s working great.
The 5 stars are for how much easier it is to care for my pool using this app and the WaterGuru Sense2 unit. No more tester strips and guessing what the more obtuse readings are (like phosphates, calcium hardness, etc). With the app I have all the info I need at my fingertips.
As for Customer Service, I would would give 6 stars if I could. I hope WG hires many more like Joan!
Altogether, this is an awesome product in my honest opinion and well worth it, even if you may have to work through some quirks in the beginning.

Hi! Susan~Thank you for your 5-star review! We're thrilled to hear that Sense2 is making pool care easier for you. We'll be sure to extend your kind words to Joan for her exceptional help. Enjoy your pool!
