To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I love this little sensor in how well it works, very sensitive, small size, fast ship from seller. My problem is that it is incredibly cheaply made. I won't even use the buttons on it to change the doorbell chime/hello greeting as I'm afraid they will simply break off. I wish the manufacturer would make a quality version of this item as I would happily pay more for it.
Ordered two of these and both would constantly go off by themselves. I tried replacing the batteries with new quality batteries but it didn't help. I live in a drafty house so thought maybe air coming around the door was sitting it off. I put them in a shoe box w/a top so I knew there wasn't anything to set them off. After all that they would still go off. I ended up sending them back.
Frustration! Opened the box, no instructions, nothing in the box but the device, no adapters, nothing else. Takes 3 triple A batteries It’s kinda like it dings when it wants, but does most of the time. Hindsight, I wouldve Spent the extra money to get better quality
Will not sense through glass, so we returned it. If i have to put it outside my door, then I can't hear it. We ordered on with a separate speaker. We wanted to use it for when our dog is at the side door, we don't forget him in the cold.
