Bitiwend Door Alarm Sensor Bitiwend Wireless Door Chime Alert for Kids Safety Home (1 Receiver+3 Sensors)

Very easy to install. Peel and stick and done. Purchased because 4 year old grandson liked to sneak outside at night and we have a pool. Base volume is adjustable and different "ring tones" can easily be heard in anywhere in our 3,500 sf house.

bought this to put on front and back doors and bedroom door for my dad who is older and likes to wander. works great and I couldn't be happier and very easy to install. definitely recommend and if needed I would purchase again

I purchased this item so that I would know if my door opens, it is very nice and has a lot of different sounds on it, but unfortunately, it will not work on my specific door, but it still gets five out of five stars

What I Like about it is easy to read guide and follow instruction. There's nothing that I disapprove of about this equipment.

Alarm works fine. However it takes an outlet, not batteries. Device does not adhere to doors or windows well. They fall apart if they fall off. Then the chase to locate and reassemble. Have had similar before for less money that lasted several years.

discount clearance rack Amazon garbage! what a waste of $28! I followed everything in the manual and found a video on YouTube,these positive reviews are fake and probably the people who work for the manufacturer and there's no way this thing was made in the USA🤣I want my money back!I had high hopes for this thing as I live alone and disabled got scammed,buyer beware!!

It's not loud enough to be an alarm to the door opening, it is barely a door chime on the loudest setting you can hear it maybe in the next room. (Definitely not upstairs!) they have to be perfectly lined up to even kind of work so if you have any door trim they don't work at all. Falls apart while trying to put the adhesive on, just cheap junk.

I have never had issues with this until super recently, the part that plugs into the wall doesn't want to act like it has power. It's “giving up” when I plug it into other outlets it does the same thing. I have had it for about a year….. and now all of the sudden I can't get it to work correctly.

Very difficult to pair a specific tone to a sensor. Sensors are too small to work on most exterior door, you know, the ones you want to alert you when the kids open them. Sensors will not properly mount if there is any type of molding on the door frame.

Alarm stopped ringing after a month, they light up but machine doesn't ring at all
