SABRE120 dB Wedge Door Stop Security Alarm, Extremely Loud Wireless Alarm Siren Audible Up To 1,500 Ft., Non-Skid Pad, Compact Alarm Great for Home, Travel, Apartment or Dorm

Great for travel and home/dorm use. The alarm is super loud. It should wake the neighbors and the dead. The batteries are not included, but are easy to buy on Amazon. Also easy to change the batteries. Highly recommend.

I recently purchased an alarm doorstop, and I couldn't be happier with my choice! It was incredibly easy to put together and came with a convenient QR code that provided access to all the information I needed. The doorstop requires a 9V battery, which was simple to install, and I was able to start using it right away. The functionality is impressive; it provides a robust alarm that enhances security without being overly complicated.What I love most about this alarm doorstop is its durability and portability. It's lightweight and easy to travel with, making it perfect for hotel stays or visits to friends and family. Plus, considering the great price, it offers fantastic value for the security it provides. I highly recommend this product to anyone looking for a reliable and effective way to enhance their home security while on the go!

Good doorstop. Loud too. Nice as an added security measure. Reasonably priced

It's simple, it's effective, but proper functioning depends on your floor surface.For those who don't want to read thru the end....Conclusion:This is a great and simple solution to keep people from entering your home, while you are at home.But you have to buy additionally a 9V block battery, need a micro screw driver to place the battery and you have to buy a simple fastener solution (see below) for slippery floor surfaces (e.g. wooden floors, stone or tiles)Delivery:I bought it on Amazon. Delivery was this time one day late.Opening:The packaging of the Alarm is tricky to open. Its completely blistered. This is not very Eco-friendly and you need strong household scissors to open it.Content:Just the Alarm, A short 1/4 page instruction.NO battery included. you need to buy a 9V block battery separately.Installation / Functioning:First you need to buy extra a 9V battery... if you realize this only after the packaging arrived, this might be quite bothersome as many households will have AAA or AA batteries always at home but not 9V block batteries.The installation of the battery requires a micro screw drive. A normal screw driver will not get you far as you wil just damage the screw head. Battery once installed you should be good to go.The alarm is loud and it works very effective.But I have a wooden floor and the device always slid away when opening the door.The rubbers on the bottom would hold strong enough to the ground.So I bought this Scotch Reclosable Fasteners, Clear, 1 x 3-Inches, 2 Sets (RF9730) to hold it strong to the ground and the door cannot slide it away.==> this works perfectly.1) The door is completely and very tight blocked! This keeps intruders from entering your home AND2) you can remove the alarm easily while this scotch fastener consist of two parts. One sticks to the floor and the other to the alarm and you can peel the device off any time easily from the floor.2) The alarm goes safely off if the door opens and cannot be switch off by the intruder - given you have placed the alarm fixed to the ground with the fastener close enough to the door.Final rating:As the obligatory 9V block battery is missing and additional investment into a fastener solution for slippery surface is needed (depending on your home) i can unfortunately only give 4 stars. Once installed properly it works perfect.Open question remaining:How long will the battery last?

This is a simple, effective product. The sound is clear and loud. No one will come throuh the front door without being noticed. Provided peace of mind. Easy to use, price was reasonable.

Easy to operate.9 V battery. When you test it, plug your ears - it is so loud your ears might burst.

I bought this thinking it was like the others we have, which make noise when you press them but stop when they are let go. These only have an on/off switch, and once it's on if you press them on accident they will not go off until you switch it to 'off'. I had given one to my dad to use, but after triggering it the first time and realizing it never goes off without manual input, I told him to just throw it away and I'd get him a different one. My dogs live with him and we both agreed it's not a good solution for someone who has pets.Pros:Does work. If it's just me, I use this in front of my bedroom door at night.Very loud!Cons:Must be switched 'off' to get it to stop making noise - this kills the ears because you have to be so close to it.Very un-friendly for animals because of the above. Imagine you accidentally leave it on, your dog somehow triggers it, and you're not back home for hours. For that reason I can't recommend this for pet owners.

Loud and long lasting. We bought this a second time. The previous one still works even after five years. The device is long and tapers to a very slim end so that it can easily fit under doors even if the gap is small. Slight negative: although the device is heavy, it is still necessary to brace something heavy against the alarm so that an intruder cannot open the door slowly and quietly the device slides away with no alarm sound if the floor is wood or ceramic.
