## At a glance

- Shows indoor and outdoor temperature and humidity alongside forecast, dew point, heat index, barometric pressure, comfort, tide level, and moon phase.
- The 7.5-inch always-on display has adjustable brightness when powered by the adapter.
- A wireless sensor is described as transmitting readings up to 330 ft and updating every 30 seconds.
- The atomic clock is designed to receive WWVB time and adjust for daylight saving time.

## Pros

- A single display brings together weather readings, clock information, and several supplementary indicators.
- Adjustable display brightness and large-font readability are practical for quick checks across a room.
- The listed sensor transmission range can help place the outdoor sensor apart from the display, within the stated range.

## Cons

- Keeping the backlight on requires the adapter, so the display is not described as a continuously lit battery-powered unit.
- The tide indicator provides a level rather than daily tide times.

## Before you buy

- The adapter powers the continuously lit backlight. Batteries are for data backup, are not included, and provide only about 10 seconds of lighting. Setup instructions describe an initial 10-minute period without updated temperature and humidity readings, and atomic synchronization may take 2–5 days. The listing also says the advertised tide indicator does not give daily tide times. Temperature accuracy is listed as 1 °C, while customer feedback reports mixed experience with outdoor temperature readings.

## In the box

- 7.5-inch display screen (Check selected pack): Listed in the package information.
- Wireless sensor (Check selected pack): Listed in the package information.
- Power adapter (Included)

## A good fit for

- Households wanting a large, adjustable-brightness display for indoor and outdoor temperature and humidity.
- Buyers who want a weather station that also displays atomic time, barometric pressure, moon phase, and a tide-level indicator.
- Fixed indoor locations with access to an outlet for continuous backlighting.

## Less suited to

- Buyers who need daily tide times, rather than a tide-level indicator.
- Those who need continuous backlighting while running the display on batteries alone.
- Anyone requiring outdoor temperature accuracy that is guaranteed beyond the listing claim and mixed feedback.

## Customer feedback

Customer feedback describes the station as easy to set up, readable, and useful for its range of displayed information, with positive comments about adjustable brightness and perceived accuracy. Temperature accuracy is mixed, including reports of outdoor-reading issues. That matters if you rely on the sensor for precise outdoor monitoring. The listing’s stated accuracy is a manufacturer claim, not a resolution of those differing experiences.
- Positive themes: Customers describe setup as easy and the display as readable in both daytime and nighttime conditions.
- Positive themes: Customers appreciate the adjustable brightness and the range of information, including moon phase, barometric pressure, and tide information.
- Positive themes: Some customers report that readings seem accurate, including comparisons with TV weather forecasts.
- Mixed feedback: Customer feedback is mixed on temperature accuracy, with some reports questioning outdoor readings.

## Frequently asked questions

### Can the display stay lit without the power adapter?
No. The listing says the adapter is needed to keep the backlight on and adjust its brightness. Batteries are for data backup, and battery lighting lasts about 10 seconds.
### Does the tide indicator show daily tide times?
No. The listing describes a tide-level indicator that updates with the date, but says it does not provide daily tide times.
### How quickly does the atomic clock synchronize?
The listing says synchronization can take 2–5 days. It also says the time and date can be set manually if synchronization takes longer than five days.
### What is included?
The manufacturer’s package information lists a 7.5-inch display screen, one wireless sensor, and a power adapter. Batteries are not included.
