Review summary

Customers appreciate the responsiveness and helpfulness of the support team and value clear communication and updates when provided. Several reviewers also mention the ease of setup, use, and management of the product. However, many customers report recurring issues with product reliability, including sensors or core units failing, short device lifespans, and manufacturing faults. There is frustration with slow shipping times, lack of tracking, delivery delays, and, in some cases, not receiving orders at all. Customers are dissatisfied with how warranty claims and refunds are handled, citing refusals, insufficient compensation, and lack of coverage for failures. Some find calibration and connection difficult or complicated. Additionally, customers feel the product is expensive considering its short lifespan, recurring issues, and lack of satisfactory compensation for failures. Issues with lack of information, unreturned emails, or difficulty reaching support are also noted.

Kwalitatief product

De sonde is niet goedkoop maar werkt wel zeer goed. Zeer tevreden van de levering. ik had bij betaald voor een snelle levering. om welke reden dan ook moest ik toch een week wachten. op éénvoudig verzoek werd de meerkost direct terug betaald.

A great product. Would had to go back to strips ...

A great product. Although I have had a few warranty failures over the years, the last failure was outside of the warranty, so I have purchased another new one. Even with the frustrations, it's still a whole lot more accurate and easier than using strips to test chemicals. I love this product.

Everything works fine, except lifetime is too short

Everything works fine. Device works well Support is quick to reply Only downside is the lifetime of the device, it only last's 1-1½ year. I have had 3 devices now.

God service. Men tilfredstillende fornøyd med ico

God service, og ico er topp når den virker. Har slitt med ph sensor og fikk ny. Men den nye ser ut til å leve sitt eget liv. Den måler opp mot ph 8-9, hopper litt opp og ned. der strips viser at ph er 7-7.2 mulig den må kalibreres? Trodde de var kalibrert fra fabrikk.

Hello Monica, thank you for your feedback. The probes are already calibrated at the factory. It is therefore not normally necessary to calibrate them upon receipt of the device. Please feel free to contact our support team so that we can look into this with you via the following link: https://ondilo.com/en/assistance/service-assistance/

Ondillo WIS Hot Tub Analyser

After about 15 months in operation, my unit would not hold a charge. It had been operating fine up until then. I did some research online and a vast number of users complained of a similar issue. When I contacted Ondilo, they said the core unit was broken & beyond repair from what data they could see online & insinuated that I had not closed the lid properly after a charge or removed the sensors and not re-installed them properly . They did offer a paltry 15% discount on a new core unit but that was the extent of their customer service. I purchased the unit when I bought my hot tub. I had initially wanted an in line unit but the sales rep convinced me that the Ondilo unit was cheaper but produced the same outcome. I wish I had stuck to my original choice . 15 months operation is laughable. If anyone is considering a purchase, my recommendation is to stay well clear of this product . I will also be surprised if this review actually appears or if it will somehow be deleted. We will see.

Hello Kieran, We’re sorry to hear that you’ve encountered a problem with ICO. As the manufacturer’s warranty is valid for 12 months, your device is unfortunately no longer covered under this warranty. We have therefore referred you to your supplier, who remains your point of contact for any further assistance. Regarding reviews, we do not remove any and respect each and every one of your reviews. Kind regards, The Ondilo team

Disappointing Warranty Handling and Misleading App Recommendation

I am very disappointed with Ondilo’s handling of my warranty case. The warranty on previously replaced parts should have been renewed for another 2 years, but Ondilo refused to honor this. On top of that, the app recommended replacing a probe, which turned out to be completely unnecessary—the probe was not defective. The real issue was with the ICO unit. To get the device working again, I ended up spending almost as much as the cost of a new device. Ondilo only offered a 30% discount on one replacement part, which I consider insufficient. To be fair, the support team was at least responsive and provided answers within an acceptable timeframe, but overall, this experience was frustrating and disappointing.

Hello, We are delighted to hear that after replacing the central part, you were able to calibrate the pH probe correctly. Our Support team remains available to answer any questions you may have. The warranty could not be applied because your ICO was a second-hand device that had been in operation since 2023.

Ik heb een nieuwe PH sensor gekocht maar werkt ook niet

Ik heb een nieuwe PH sensor via jullie gekocht, maar deze werkt ook niet. Bij de kalibratie met de PH4 vloeistof geeft het systeem aan dat het 13 is. Dus nieuwe sensor werkt ook niet. Wat moet ik nu doen ? Kan ik sensor ergens gaan wisselen in een verkooppunt waar ze mij helpen? Ik zou graag ergens persoonlijk geholpen worden i.p.v via een formulier invullen of chatten .

First product was sold to me under the wellis brand in 2023. This failed in 2024, so a replacement probe was sent out. This did not work, so a whole new core device was sent under warranty. This lasted another 18 months and has now started to fail. Despite me spending £80+ on a replacement probe, I was then told the device has failed again, and the customer support team offered me 30% off a replacement. Two weeks on, after a lot of toing and froing on the tracking, the tracking suggests the parcel is going back to the sender! Despite not even making it out of France. Support is difficult to reach, and is slow to reply. The devices don’t last. It’s a fantastic product when it works but it fails too often. There doesn’t seem to be a decent cost effective alternative…
