Everything works well. Only downside is product lifetime, only last approx 1 year

Paid infull for 2 calibration kits for the smart water monitor and over a month later still not arrived. Ordered on 7th of August, now 6th of September with no update

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.

Extremely poor. I have had three units in two years and the last one has just died. Customer service is slow to respond, if they bother at all.

Extremely slow response. Hard to get hold of. Started a ticket in May and still not resolved (September).

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.

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 .

Product does not work, despite two replacement PH probes.

Shipping takes long time and the price you get is without taxes

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…
