Prime members are eligible for free shipping according to the source; check the offer's availability and whether you need the separately sold Ring subscription for Professional Monitoring. Best suited for: Shoppers seeking alerts for an outdoor entry point, such as a gate, shed, or garage, without adding a base station. ### Why It’s Worth Buying - The sensor sends alerts when an outdoor entry opens, which may help monitor gates, sheds, or garages. - The source describes it as weather-resistant (IP66) and rated for conditions from -4°F to 120°F, relevant for outdoor placement. - It works without a base station, so the source does not indicate a separate base station is needed for this sensor. ### Why the Price Makes Sense The source reports a $23 price against a $40 reference and says it is below the 90-day average of $30. These are source-reported figures, not merchant-verified pricing or proof of a usual market price. Free shipping is reported for Prime members; no other shipping terms are supplied. ### Consider before buying - Free shipping is limited to Prime members, according to the source. - Professional Monitoring requires a compatible Ring subscription and is sold separately. - The source says the battery is rated for up to 10 years; actual battery life is not established. ## Evidence and sources The merchant check failed. This does not prove expiration; the previous successful verification time is retained.
