the device is great for waking up my daughter
the device is great for waking up my daughter, even though its loud but i think if it wasnt it wouldnt wake up the child...there is an option for sound and vibrate or for vibrate only...it is a bit hard when you try to lock it with the panty....i gave it a 4 star because within 2 weeks it stopped working, its very delicate that i think the wire got disconnected from the inside of the lock.
Rating: 4 stars
