Helpful, but app needs work

I recently purchased the WaterGuru SENSE S2 and a Replacement Cassette 3-Pack. The device itself is quite good at giving accurate readings for free chlorine and pH, and the daily updates are genuinely convenient. Delivery was prompt, no issues there. However, the mobile app could use some polishing. While it provides chemical recommendations, navigating through past data or understanding some of the charts felt a bit clunky. It's not a deal-breaker, as the core functionality is solid, but improving the app's user experience would make it a truly excellent product. Customer service was responsive when I had a question about cassette installation.

Always reliable, great for upkeep

I've been using WaterGuru for a while now, this was my third SENSE Cassette Refill order. Just like before, everything arrived quickly and was exactly what I needed. Their system keeps my pool perfectly balanced, and I've never had an issue with consistency. Makes pool maintenance so much easier.

Decent service, quick delivery

Ordered the WaterGuru SENSE S2 after seeing a friend's setup. The ordering process was straightforward on their website, no hitches there. Delivery took about 5 days to reach Denver, which was reasonable. Setup was pretty intuitive with the app instructions. The device itself seems well-built, and the initial readings lined up with my old test kit. I had a quick question about calibrating the pH sensor, and customer support got back to me within a day with clear steps. So far, the automated testing is a big time saver for me, and the app's recommendations are easy to follow. Quality seems good, and it's definitely simplified my weekly pool routine.

Good value with the bundle

I was looking for a smart pool monitor and the WaterGuru SENSE S2 bundle caught my eye during a holiday promotion. It included the device and a 3-pack of cassette refills, which felt like a solid deal. The initial discount saved me a decent amount compared to buying everything separately. I really appreciated not having to buy refills right away. The shipping was free, which always helps the budget. Overall, it felt like a worthwhile investment for what I paid, especially with the included supplies.

Easy pool testing now

Got a WaterGuru SENSE a few weeks ago. It's actually pretty cool. You just pop it in the skimmer and it does its thing. The app tells you what's up with your pool water. No more fiddling with those little test strips. Made pool chores way less annoying.

Do I need to pay for a subscription to use the app and get the recommendations? Or is that all included?

N Nina 2 months ago
The basic app features and recommendations are included with the device, you don't pay extra for that. You just need to buy the refill cassettes.

J James Romero 2 months ago
Nope, no monthly fee for the app itself! Just buy the refills when you need them. Pretty sweet deal actually.

how does this compare to something like Sutro? I'm trying to decide between the two.

R Ryan R. 2 months ago
Sutro is definitely pricier. WaterGuru is more focused on the core measurements and recommendations, I think. Sutro has a few more bells and whistles but I didn't need them.

I looked at both. WaterGuru seemed simpler to set up and use, plus the cassette system is pretty convenient. Sutro felt a bit overkill for my needs.

Does WaterGuru ever do new customer discounts? Or like, a first-time buyer code?

J Jared Marsh 2 months ago
They sometimes have bundle deals or a referral thing if you know someone. Not always a straight-up 'new customer' code though.

I got 10% off my first cassette refill order but I think that was part of a larger promo. For the hardware, keep an eye out for seasonal sales.

Thinking of getting the WaterGuru SENSE S2 but I'm worried about returns if it doesn't work out. What's their policy like?

J James Romero 2 months ago
I returned one last year. It was pretty straightforward, just make sure you keep the original packaging. They give you a window to do it.

Is WaterGuru actually good for salt water pools? Some of these testers get weird with salt.

N Noor Doyle 2 months ago
Yeah, it totally works for salt pools! My pool is saltwater and it's been fine, no issues at all.

I've got a saltwater system and it reads everything correctly. Been using it for months without a hitch.

Anyone know how long shipping usually takes for the SENSE S2 to, say, Miami?

N Noor L. 2 months ago
Mine took about a week to get to Florida. I think it depends on their stock sometimes.
