Excellent alarm and amazing customer service
First off, I love this alarm. I have a detached storage room and I was looking for a self contained alarm. This one is exactly what I was looking for. Super easy to set up and works exactly how it should. I did have an issue where one of the buttons on the remote would intermittently stick. I emailed their support department and received a reply right away. Cindy (customer service) was so nice to work with, she apologized and didn’t hesitate to make it right. She said that they would immediately send out a new remote. What I received was a complete new unit and a spare remote. If you’re looking for a great self contained alarm and excellent customer service, look no further. They are the best!

Customer service was fantastic!!
Bought two of these thinking the first was defective. It must not have been. Both worked the same- they did not allow the 1 second delay. I wanted something to go off quickly, not wait 5 seconds. Their customer support reached out to me and offered to send a new replacement one. This new one works perfectly now. Their customer service is amazing- they reached out to me proactively and send the new one quickly! Thank you!

A Keeper !!!
Good price & value with fast service……….. EZ install …..We were having a nocturnal racoon or possum getting into our trash cans that are stored in a 2 can plastic storage shed. Installed this alarm and the next morning there was evidence of animal entry and very hasty departure. Its been over a week now with no friendly visits. Very easy to install & operate. Worth every penny of this low cost alarm. We highly recommend trying this unit.

Good Customer Service
Initial Review: The quality of the remote that is used to activate the system leaves something to be desired. The activate or (Lock) button continually sticks. Amended Review: After contacting the seller and explaining the issue a replacement remote was sent and received. The new remote works correctly and the issue has been resolved. The service representative was very helpful and followed through.

Worth Every Star
Works great. I combined this with a motion light. If the light doesn’t scare them off and they continue to advance, this thing starts to squeal and it’s just the right about of noise. It worked straight out of the box, zero config. Remote has two buttons: Armed, Unarmed. Just what I wanted. Something simple and reliable. So far, this thing is just what the doctor ordered.

I can’t get the wall mount to mate with the bracket.
The mount doesn’t seem to mate with the bracket. The remote button gets swiveled a bit and doesn’t work unless it is swiveled back to position. Otherwise it does function.

Loud, Simple Motion Alarm — Great Extra Layer of Security
Why I Got This:I wanted a small, portable alarm to add an extra layer of security for areas like the garage and when traveling. I didn’t need a full smart system or app — just something loud, reliable, and easy to use.What I Liked:The alarm is extremely loud when triggered — the 135dB siren definitely gets attention and would be enough to scare off an intruder or alert people nearby. Setup is straightforward, and I appreciate that it uses a keypad instead of a remote or app, which makes it simple for anyone in the household to operate. The adjustable sound levels and the option to switch between alarm and chime modes add flexibility depending on how you want to use it.It’s lightweight and portable, which makes it handy for travel, camping, RVs, or temporary setups. I also like the 30-second exit delay, which gives you time to leave the area without setting it off.What Could Be Better:This is a basic, standalone alarm — there’s no remote included with the single-unit version, and it doesn’t come with batteries. It’s also not waterproof, so it’s strictly for indoor or covered areas. Motion sensitivity can be affected by heat, so placement takes a little trial and error to avoid false triggers.Bottom Line:If you’re looking for a simple, affordable motion sensor alarm to boost security in a garage, shed, room, or while traveling, this Mosaic Alarm does the job well. It’s loud, easy to use, and dependable as a secondary security solution — just don’t expect smart-home features or outdoor durability.

Fonctionne très bien

Der Einbruchsalarm mit Bewegungssensor wird mit einer 4seitigen Bedienungsanleitung (in englisch) und Befestigungsmaterial (2 Schrauben/2 Dübel) geliefert. Mal eben die Anleitung überflogen, 2 x AAA Batterien eingelegt und nach kurzer Zeit ist der kleine und mobile Apparat scharf geschaltet und überall einsetzbar.Er überwacht zuverlässig die Garage, die Hintertür des Hauses oder auf Reisen das Zelt o.ä. und schützt vor Eindringlingen (menschlich oder tierisch). Im Falle eines Falles löst er durch den reaktionsschnellen Sensor den Alarm aus. Ob das wirklich 135dB sind, kann ich nicht beurteilen. Auf jeden Fall so laut, dass es definitiv abschreckt! Aber keine Bange: die Lautstärke ist in 3 Stufen einstellbar: High/Medium/Low. Ebenso in 2 Bereiche ist die Überwachungsdistanz einstellbar: 9Meter/3-5Meter oder der Sound bei Auslösung: Alarmton/Klingelton (nützlich wenn man das Gerät als Haustür Bewegungsmelder nutzt).Für den aktuellen Preis von 16,99€ ein tolles Sicherheits-Gadget!.
