Window/door sensors

Seems to work really well had no false alarms and notifications and chimes work with no issues highly recommended still waiting for external siren to be available though

Small but effective

Does the job.
The alarm only sounds in the homebase not in the sensor. Still very loud but if the homebase is not near the entry point, the intruder may not be deterred.
Taking the cover to insert battery was not the simplest.

Good sensor

Good sensor, although it would be nice to change the notification sound on my mobile so i can tell it's the entry sensor triggered and not any other notification on my phone.
Also sometimes i don't get a notification of it opening but i think it may be my signal or app delay
