These ARE LOUD!! They definitely get the job done. Easy to use. They are peel and stick; however also come with little screws, so you have options on how to install. The instructions were quite clear and we had them set up in a few minutes. The biggest take away I cannot stress enough, they are loud. The remote lets you adjust the volume though. They are definitely worth it. They also don’t take up a lot of space and aren’t super noticeable where we placed them. We didn’t use the screws and our front door gets a lot of traffic and the peel and stick adhesive has been absolutely fine. I think maybe the only thing people may find to be an issue is possibly with placement. Our back door the frame didn’t allow for a proper alignment, but it was close enough that it still works without issue. The lip of the frame didn’t fit the width of the magnet without knocking it off when the door was opened. We moved it to on the actual door frame and even though it doesn’t line up like the one in the photo (our front door), the magnet is strong enough that it works still. It’s one top left hand side of the door.

Works well so far and very loud but that is what I wanted. Easy to put on my doors. You can turn them off if you have a lot of traffic during the day and only want them activated at night.

PROS: Easy installation. I installed two alarms on both my doors in about 5 mins. The box included a remote, the host (big white box that goes on door), magnet box (slinder white strip), and 3 adhesive strips. Remote is already programmed to the alarm, so no need to do that. Adhesive strips seem to hold well. Alarm is loud...very loud. Remote is also very sleek looking and resembles the keyless remote to my car. And yes, you can put it on your keychain. CONS: Although I appreciate the loudness when the alarm is in armed mode, it is WAY too loud for just the normal doorbell function which alerts you the door is being opened. I don’t even use this function for that reason. If you have more than one alarm (as I do) you have the ability of pairing one remote to multiple alarms. However, the downfall of this is that whatever mode you put the paired remote on, this mode will apply to any alarms paired to that remote. Just because I want to arm my front door at night doesn’t mean I want to arm the door of my child’s bedroom as well. I just want to be alerted that he is trying to get out of his room (via doorbell mode). After finding this out I had to unpair the remote and repair them with their own individual alarm. Despite the cons, I find the pros outweigh the cons. It’s well priced and seems to be of good quality. Granted I’ve only had it for one day, but so far so good.

One of the best, have it for 3years. Replace battery once year on alarm part. Work great.

I tried out a few different options for a DIY home alarm system and these were the ones that absolutely fit the bill. I started out with a pair of them to test out and ended up buying 3 more sets. Why? 1) Extremely easy to set up. There is a little give in the space needed between the magnets and the actual alarm, so if your windows/ doors and frames aren't flush, no problem 2) Range! I can arm and disarm the units in my basement from my second floor. I was very surprised and happy about this! 3) Compatibility of components- I had to watch a Youtube video to learn how to do this, but it turns out, you can pair every single transmitter to work with ALL the alarms, and ALL transmitters can be paired to activate every single alarm. 4) Abundance of key fob transmitters. Every alarm comes with a transmitter so everyone in the family can have one that works the same as the next 5) Panic button: because I can activate the alarms from such a long distance, I use one of the transmitters as a panic button in my bedroom. If I hit the "lightning bolt" button, I can get ALL the alarms in the entire house to go off together. If that doesn't scare the $%#t out of an intruder, then nothing will. 6) Doorbell function: you can set the alarms to give off a double ring, just to alert you when someone opens a door or window. It's pretty loud, but would be good if you're outside or in the basement and want an alert of this kind. 7) Cost: I paid a lot more more for a lot less when I first started testing out different components for my home security. I returned the others after I saw what this system could do. 8) Power: I like that they run on batteries, so if power gets cut, they will still work. Cons? No internet alerts when your system gets set off. This is a real time, intruder focused system, not a monitoring system (so no monthly fees- another pro). To address this, I also bought a couple of Reolink security cameras to provide eyes into my home. They alert me if motion is detected inside the house. Because it has 2-way audio, I should be hearing a hell of a racket if someone actually gets in. Anyway, I am very happy with the synergy between these two systems.

I ordered these for my daughters apartment. I asked her one week after getting and she said the door that is used more was no longer up due of the sticky back not working. I had to run to store to buy a more secure way to keep it up. The loudness is good, loud enough for everyone to hear and size is perfect.

Triple AAA batteries are used in unit not weird LR44. However that is what remote uses. Have not accessed remote batteries. This is a loud alarm which is useful. You cannot adjust volume.So if you have babies and you need to disarm alarm it is loud to disarm. I have no babies to worry about. See pictures for mounting help. My door FRAME is rounded molding. Attach the function unit on the flat door and the the small receiving unit on the rounded frame. I gave three stars because one unit continually flashes even when disarmed. The batteries drain within a week. I couldn't find any contact info for the company so I am stuck with this defective unit. The other one is fine. I like the remote function. I can arm and disarm without having to reach high every time. But quality is lacking. You will see in pic that I have placed a magnet under the door unit. This door gets slammed a lot and adhesion was a problem until I added this magnet support. I have changed my review after Hendun reached out to me saying my unit was still under warranty. Very happy about that. They have solved my issue. Thank you Hendun.

Have used these alarms for some years, totally meet my needs. They are loud ( but have adjustable sounds, including doorbell)

La alarma funciona bastante bien, tiene un sonido fuerte, lo unico que no me agradó mucho es que la alarma deja de sonar si vuelves a cerrar la puerta o ventana. Una de las alarmas venia con parches de pegamento viejo (tuve que retirarlos con calor y ponerle nuevos) pero en general cumplen con la función de "alarmar" y que se percibia la alarma en toda la casa.

Ein kleiner Schutz für zu Hause. Wenn jemand abends die Türe öffnet bist du wach. Tolles Produkt einfach zu befestigen

Had these on about a year now and really impressed, they are SO loud! We use them on our front and back door for extra peace of mind. Easy enough to put on and they've stayed on for a year and still going strong. Really impressed and definitely recommend for extra precaution, especailly becasue we have pets so we can't turn our alarm on at night so this is just nice to have and we know it will wake us up!

Der HENDUN Kabellose Türalarm hat meine Erwartungen voll erfüllt. Die Installation war kinderleicht und in nur wenigen Minuten erledigt. Man muss lediglich den Hauptalarm und den Magnetsensor an Tür oder Fenster kleben – ganz ohne Bohren oder aufwändiges Kabelverlegen. Das System war sofort einsatzbereit. Die mitgelieferte Fernbedienung ist sehr praktisch. Man kann den Alarm einfach scharf- und unscharf stellen, was im Alltag sehr komfortabel ist. Was mich besonders beeindruckt hat, ist die Lautstärke des Alarms – mit über 100 dB ist er wirklich ohrenbetäubend und schreckt potenzielle Eindringlinge effektiv ab.
