Great Purchase, great price!
Great purchase at a great price. I highly recommend. I like the fact that they are easy to install and there a few alarm options. One that sounds once the door is open and then it stops and another the keeps ringing while the door is open. They have 3 different volume options and there is also a shut off option which is nice because I got these for when my grandbaby is visiting.

Good quality and function
You can adjust to listen to different kinds of alarms and you can also adjust the loudness as well. These are easy to use and easy to set up. Every time you open the door you hear a ring so you know the door has been open so it gives you peace of mind. These function well as a door alarm when the door is open. I bought them because my 5-year-old likes to go outside and that way I can hear when the door is opened. These came in three of a pack and I definitely recommend them for doors or windows

Adhesive fails
These are inexpensive and effective little alarms, but the adhesive on the narrow part of the alarm fails quickly so be prepared to attach them some other way. I think it’s because the little side of the alarm is so small that there just isn’t a lot of surface area for any kind of adhesive. They’re loud enough to alert your household, but not enough to annoy your neighbors. Overall a decent product, but the adhesive failure is a problem.

highly recommend
This are a wonderful addition to my home. I have added to my doors to protect my grandchildren from entering my pool area without adults knowledge. They have also become an extra layer of security in my home. So easy to install on regular doors and patio door. I like the multiple settings. Very loud setting is great when you have a house full of people and want to know who is coming and going. They are very discreet which is also a plus and can be mounted high out of the reach of children.

Door & window alarms
These are perfect to let us know when someone has opened a door or window out to the pool. Small ones can not sneak out. Easy to install, turns off when needed.

Feeling secure
Easy to install. Uses secure adhesive strips. Alarms are loud and let me know when my little eloper tries to leave. As a mother with a disabled child this gives me comfort.

Ich habe mir das Gerät zugelegt um eine akzeptable Soundausgabe für ein kleines, Raspberry Pi 3B+ basiertes Media System mit 7″ Screen zu haben. Die Soundkarte wurde vom System problemlos als Audiogerät erkannt und nach Eintrag in die ALSA hat sie auch sofort funktioniert ( Tutorials zur Installation von USB Soundkarten unter Linux gibt es im Netz). Der Sound ist absolut okay, Arien würde ich jetzt keine über die Karte hören aber dazu ist sie auch nicht gedacht. Der Stromverbrauch ist auch moderat genug um sie an einem Raspberry Pi ohne zusätzlichen aktiven USB Hub zusammen mit zusätzlichen USB Peripherie Geräten betreiben zu könnenPlane noch ein paar ähnliche Projekte und ich werde sie mir dafür wieder kaufen!

Easily set up, adhesion is spot on, think people having issues with this could be due to not cleaning down the frames ect. Bit more security during the night

Good for our front door. Stuck well to the upvc frame and door.Relatively discreet too.

Ich habe mir den Adapter für die zusätzliche Soundausgabe an der Nintendo Switch gekauft. Da ich den Sound über HDMI nicht direkt auf meiner Anlage ausgeben kann und der in der Switch integrierte Miniklinkenanschluss eine Brummschleife verursachte, war eine andere Lösung notwendig. Aus diversen Foren war mir bekannt, dass die Switch in Verbindung mit dem Dock PlugNPlay-USB-Sound-Adapter unterstützt, es gab jedoch wenig Informationen darüber, ob es bei der Auswahl des richtigen Adapters Einschränkungen gibt.Nach längerer Suche bin ich auf den TechRise Adapter gestoßen und bei diesem Preis konnte man nicht viel falsch machen.Nach Eintreffen der Bestellung direkt ausgepackt und angeschlossen und es hat sofort funktioniert. Die Switch erkennt den Adapter als USB-Soundkarte und die Tonausgabe ist einwandfrei.Ich habe den Adapter bisher nicht an anderen Geräten (z.B. Windows-PCs) getestet, jedoch gehe ich davon aus, dass dieser dort auch ohne Probleme funktioniert.Für diesen Preis macht man auf jeden Fall nichts falsch!
