Easy DIY alarm
It’s been almost a month now and it work really good. Easy to install (the manual is not all that good, but there are plenty of videos around to figure out how to install and configure all). And you can check all from the app too.

It’s very loud, supports multiple languages, and comes with 6 alarms and 3 infrared sensors, offering a variety of functions.

Doesn’t work
It has a nice appearance but doesn’t work, the alarm turns on on its own even when not armed…Don’t loose your money like I did!

Worked perfectly with my existing system
I picked these up as extra sensors for my existing YBJ alarm system, and they worked exactly how I needed them to. Pairing them with the panel was pretty straightforward, and once they were connected, they responded right away when doors or windows were opened.Installation was super simple too, just peel and stick. They’re lightweight and don’t stand out much, so they blend in fine on doors and window frames. The connection has been solid so far with no random dropouts or missed alerts.One thing to keep in mind is that these won’t work on their own, you do need a compatible alarm system for them to connect to. As long as you already have that, they’re a really easy way to expand your setup without much hassle.If you’re already using a YBJ system and need more sensors, these are a solid choice.

Tough programming
Nice packaging fast shipping looks great but the instructions are not only a little vague but very hard to follow on seeing your phone up as every phone is a Lil different, getting it programmed not to go off in home mode took 2 days. Not for beginners, you need to be competent on following directions to the letter and even then it is not always what they say it is on outcome, alarm went off a lot trying to figure it out and it is loud.Would recommend for beginner systems
