What to know before buying
Listing details to confirm
The base station requirement is clear for app functions, but listing details conflict: the title and colour field describe a three-pack with the SBS50 required, and an app note says the station is not included, while the included-components list states one SBS50 base station and four water sensors. The number of sensors also differs from the three-pack title. Confirm the selected listing's kit before buying. The listed dimensions and ceiling-mount type are also inconsistent with the feature description of a slim sensor for tight spaces, so check the sensor's actual dimensions and installation method.

Customer feedback reports good perceived quality and ease of setup. Those points may matter for users placing sensors around a home, while the conflicting package details and the base-station requirement remain important buying checks. Aggregate ratings are largely in the five-star category, but also include a small one-star share and do not establish why customers rated the product as they did.
Positive themes
- Customer feedback describes the detector as good quality.
- Customer feedback describes setup as easy.
Frequently asked questions
Does the detector need a base station for app alerts?
Yes. The listing says the SBS50 base station is required to use app features. Whether it is included in this selected package is contradictory, so confirm the kit contents before buying.
How does the sensor detect water?
The listing describes two probes on top and four underneath, with detection claimed for water as shallow as 0.3 mm and for drips from above.
How many sensors are in the package?
The title identifies a three-pack, but the included-components list says four water sensors. The quantity is therefore unconfirmed and should be checked against the selected listing.
Can it sound an alarm without the app?
The listing says the base station sounds an alarm up to 100 dB when a leak is detected. The base station's inclusion in this package is unclear.
