What to know before buying

Listing details to confirm

The listing presents 130 dB, an over-one-hour strobe duration and IP65 resistance as claims, not independently measured results. Location notifications and the arrival reminder are not the same function. Only the reminder is explicitly stated to require a SwitchBot Hub, so check how location notifications work before relying on them. The alarm is described as a keychain, but technical details also list wall mounting and a contact sensor, whose relevance to this product is unclear.

Aggregate ratings are mixed overall: the majority fall in the four- or five-star categories, while a substantial share are three stars or below. Ratings alone do not show why customers were satisfied or dissatisfied. For a device where sound output, strobe operation and alert functions matter, these figures cannot confirm how it performs in use.

Frequently asked questions

Does the alarm provide location notifications?

The title and listing claim location notifications, but the supplied details do not explain how they are enabled or whether they require a Hub. Check the selected product information before relying on this function.

Is a SwitchBot Hub needed?

The listing specifically says a SwitchBot Hub enables a home-arrival reminder. It does not clearly establish that a Hub is required for the alarm or all location notifications.

What does the listing say about the siren and strobe?

It claims a 130 dB alarm and says the strobe flashes for over 1 hour. These are listing claims rather than independently verified performance.

Are batteries included?

The battery specification says two nonstandard alkaline batteries are required and included.
